Keeping IT Running: Service Management and Network Administration
By vaayaa Editorial Team · Subject panel: Hiroshi Tanaka (PhD, Computer Science), Carlos García (Master's, Data Science)
IT service management, enterprise IT operations, and network and systems administration are three overlapping disciplines that together keep organisations running. Each has distinct roles, tools, and career trajectories, but all three reward structured thinking, process discipline, and a willingness to own problems end to end.
Key takeaways
- The global ITSM software market was valued at roughly USD 11.91 billion in 2024 and is projected to grow at a CAGR of around 15 percent through 2032, driven by cloud adoption and AI-assisted automation.
- Computer and information systems managers earned a US median wage of USD 175,140 in May 2025, with employment projected to grow 16 percent from 2025 to 2035.
- Network and computer systems administrators earned a US median wage of USD 99,130 in May 2025; the BLS projects a 4 percent employment decline by 2035, though roughly 13,400 openings are still expected annually from retirements and role transitions.
- ITIL 4 remains the dominant framework for ITSM practice, with a certification ladder from Foundation through Managing Professional, Strategic Leader, Practice Manager, and Master.
- The three fields converge at the enterprise operations layer, where service management processes, infrastructure reliability, and business continuity must work in concert.
- Professionals who combine ITSM process knowledge with hands-on infrastructure skills are well positioned for senior operations, cloud, and service delivery roles.
Every time a user submits a support ticket, a router forwards a packet, or a change is approved for production, three disciplines are at work: IT service management, enterprise IT operations, and network and systems administration. These are not glamorous in the way that software development or data science tend to be, but they are foundational. Without them, the applications built by developers never reach users reliably, the data analysed by scientists never arrives intact, and the business never meets its uptime commitments. The IT Service Management programme covers this in depth, building the structured discipline that transforms IT from a technology supplier into a service provider delivering measurable business value.
This discourse covers all three fields in enough detail for a student choosing a direction, a working professional deciding what to study next, and a career changer assessing where their existing skills transfer. The labour market data comes from the US Bureau of Labor Statistics, the ITSM market figures from Fortune Business Insights and related research firms, and the framework guidance from PeopleCert and the ITIL body of knowledge. Every number is sourced; none is invented.
What These Three Fields Are and How They Relate
IT service management (ITSM) is the discipline of designing, delivering, managing, and improving IT services so that they meet agreed business needs. It is primarily a process and governance discipline, not a hands-on technical one, though practitioners must understand the technology they are managing. The dominant framework is ITIL 4, which organises practice into a service value chain and a set of management practices covering everything from incident handling to continual improvement.
Enterprise IT operations sits one level above day-to-day administration. It integrates ITSM processes with the broader operational management of infrastructure, applications, and vendor relationships across a large organisation. Where ITSM defines the rules of the game, enterprise operations runs the game at scale, connecting service management to business continuity, capacity planning, and financial accountability.
Network and systems administration is the hands-on discipline of installing, configuring, and maintaining the hardware and software that organisations depend on. Network and computer systems administrators install, configure, and maintain organisations' computer networks and systems [18]. They work at the infrastructure layer that ITSM processes govern and that enterprise operations coordinates. The three fields are therefore nested: administration provides the infrastructure, ITSM provides the process framework, and enterprise operations provides the strategic integration.
Fact The US Bureau of Labor Statistics reported a median annual wage of USD 99,130 for network and computer systems administrators in May 2025, and USD 175,140 for computer and information systems managers in the same period. Both figures come from the BLS Occupational Outlook Handbook, May 2025 release [10][2].
Computer and information systems managers earn nearly 3.4 times the all-occupations median, illustrating the wage premium for senior ITSM and operations leadership.

IT Service Management: Process, Frameworks, and Careers
ITSM is the practice layer that turns raw IT capability into reliable, measurable service. Its core concern is not whether a server is running but whether the service that server supports is meeting the commitments made to the business. That distinction drives everything: the language shifts from uptime to availability, from tickets to incidents and requests, from fixes to problem resolution and root cause elimination.
Where ITSM Is Used and Why It Is Growing
ITSM adoption spans enterprises, government, healthcare, finance, education, and managed service providers, and the work connects directly to business uptime, user experience, and risk management [5]. The global ITSM market was valued at USD 11.91 billion in 2024 and is projected to grow from USD 13.58 billion in 2025 to USD 36.78 billion by 2032, at a compound annual growth rate of 15.3 percent. North America held a 43.16 percent share of that market in 2024. Cloud-based deployment now dominates the software segment, accounting for an 86 percent market share according to one 2024 analysis.
Estimate Market size figures for ITSM vary across research firms depending on how they define the segment. Fortune Business Insights valued the total ITSM market at USD 11.91 billion in 2024, while other firms report narrower software-only figures. The 15.3 percent CAGR projection should be treated as an indicative range, not a precise forecast.
The growth is being driven by rising incident volumes, with one market report noting a 22 percent increase in incident volumes in 2024 alone, and by the expansion of automation and self-service portals, which grew to 64 percent adoption among large enterprises in the same period. Organisations are also increasing ITSM budgets: 59 percent of companies reported doing so in 2024.
Typical Roles and Day-to-Day Work
The ITIL 4 framework maps roles across three broad levels. At the entry level, a Service Desk Analyst is the first structured contact point between users and IT, handling incidents and requests, documenting symptoms, categorising tickets, applying first-line fixes, escalating when needed, and keeping users informed. At the specialist level, roles such as Incident Manager, Problem Manager, Change Manager, and Configuration Manager own specific ITSM practices. At the leadership level, Service Delivery Managers and IT Operations Managers own service health, stakeholder trust, and the improvement roadmap.
- Service Desk Analyst: first-line triage, ticket logging, user communication, knowledge base use
- Incident Manager: owns the incident lifecycle from detection to closure, coordinates resolution teams
- Problem Manager: investigates recurring incidents, conducts root cause analysis, manages known errors
- Change Manager: assesses risk and authorises changes to production environments
- Service Delivery Manager: owns SLA compliance, stakeholder relationships, and service reporting
- IT Operations Manager: oversees daily operations, capacity, and availability across services
Core Skills and Tools
ITSM practitioners need a combination of process knowledge, communication skill, and platform fluency. The ITIL 4 framework is the dominant knowledge standard, with a certification ladder running from Foundation through Managing Professional, Strategic Leader, Practice Manager, and Master. The Foundation level gives the basics; Managing Professional covers service management and team leadership; Strategic Leader addresses how IT aligns with broader business strategy. Tools in daily use include ITSM platforms such as ServiceNow, Jira Service Management, and BMC Remedy, alongside monitoring and event management systems.
The free first section of IT Service Management gives a practical preview of how these concepts are structured before committing to the full programme.
Senior ITSM and operations management roles are growing at more than five times the all-occupations rate, while traditional network administration is contracting as cloud automation reduces routine tasks.

IT Service Management and Enterprise Operations: Scaling ITSM Across the Organisation
Enterprise operations is where ITSM principles meet the complexity of a large, multi-system, multi-vendor organisation. The challenge is not just running good processes in one team but integrating service management across business units, geographies, and technology stacks. The IT Service Management and Enterprise Operations programme addresses exactly this integration challenge, giving practitioners the knowledge to lead that transformation.
What Enterprise Operations Adds to ITSM
At the enterprise level, ITSM expands to include service portfolio management, IT financial management, supplier management, and business relationship management. The service catalogue becomes a strategic document that defines what IT offers, at what cost, and under what conditions. Service level agreements are negotiated with business units rather than simply imposed. The information sector is projected to be the third-fastest growing sector of the US economy between 2024 and 2034, with employment growing at a much faster-than-average pace of 6.5 percent [6], and enterprise operations roles sit at the centre of that growth.
Computer and information systems managers, the BLS category that most closely maps to senior enterprise operations roles, held about 685,800 jobs in the US in 2025 [2]. Employment in this category is projected to grow 16 percent from 2025 to 2035, much faster than the average for all occupations, with about 53,500 openings projected each year [2]. The median annual wage was USD 175,140 in May 2025, with the information sector paying a median of USD 200,510 [2].
Typical Roles and Day-to-Day Work
Enterprise operations professionals spend their days at the intersection of technology and business. An IT Operations Manager reviews overnight monitoring alerts, chairs a daily stand-up with service owners, reviews a change advisory board agenda, and prepares a monthly service report for the CIO. A Service Portfolio Manager works with business stakeholders to define new service requirements, assesses the cost and risk of adding them to the catalogue, and tracks the retirement of legacy services. A Continual Service Improvement Manager analyses trend data from the ITSM platform, identifies patterns in recurring incidents, and builds a case for process or tooling changes.
- IT Operations Manager: owns daily service health, chairs change advisory board, reports to senior leadership
- Service Portfolio Manager: manages the lifecycle of services from concept through retirement
- Continual Improvement Manager: analyses metrics, identifies improvement opportunities, tracks outcomes
- IT Financial Manager: tracks IT costs against budgets, builds business cases for investment
- Business Relationship Manager: acts as the interface between IT and business units, manages expectations
Core Skills and Tools
Enterprise operations demands a broader skill set than entry-level ITSM. Practitioners need strong data literacy to interpret service metrics and build improvement cases, financial acumen to manage IT budgets and articulate return on investment, and stakeholder management skills to work across business units. ITIL 4 Managing Professional and Strategic Leader designations are the standard credentials at this level. Tools include enterprise ITSM platforms, configuration management databases (CMDBs), IT financial management software, and business intelligence dashboards.
Opinion Many organisations still treat IT operations as a cost centre rather than a value-generating function. The shift to service-oriented thinking, where IT is measured by business outcomes rather than technical metrics, is the central cultural challenge in enterprise operations. This is a widely held view among ITSM practitioners and consultants, but it is not a measurable fact.
The ITSM market is on track to more than triple between 2024 and 2032, reflecting sustained enterprise investment in structured service management as organisations scale cloud and AI-driven operations.

Systems and Network Administration: Building and Maintaining the Infrastructure
Network and systems administration is the hands-on discipline that keeps the physical and virtual infrastructure running. Administrators install, configure, and maintain servers, switches, routers, firewalls, storage systems, and the operating systems and services that run on them. The Systems and Network Administration programme builds this infrastructure practice from design through deployment and ongoing maintenance.
Where Administrators Work and What They Do
Network and computer systems administrators work for a variety of organisations, including computer systems design firms, schools, and financial institutions [18]. Most work full time, and some work more than 40 hours per week; administrators may work evenings, nights, and weekends to monitor, maintain, or update networks and systems [18]. The work is reactive as well as proactive: responding to outages, applying security patches, and troubleshooting connectivity problems sit alongside planned work such as hardware refreshes, capacity upgrades, and configuration audits.
The BLS reported 323,600 network and computer systems administrator jobs in the US in 2025 [10]. The median annual wage was USD 99,130 in May 2025, with the lowest 10 percent earning less than USD 62,640 and the highest 10 percent earning more than USD 155,050 [10]. Employment is projected to decline 4 percent from 2025 to 2035, though despite this decline, about 13,400 openings are projected each year from retirements and role transitions [10].
Fact The BLS projects a 4 percent employment decline for network and computer systems administrators from 2025 to 2035, driven by automation and cloud consolidation. However, 13,400 annual openings are still expected, all from replacement demand rather than new job creation [10]. Administrators who develop cloud and security skills are better positioned for adjacent roles in cloud networking and security engineering [11].
Typical Roles and Day-to-Day Work
A systems administrator's day might begin with reviewing overnight monitoring alerts, applying a patch to a group of servers, provisioning a new user account in Active Directory, and troubleshooting a VPN connectivity issue reported by a remote worker. A network administrator might spend the morning reviewing firewall logs, updating routing tables after a network change, and testing a new switch configuration in a lab environment before pushing it to production. Senior administrators spend more time on architecture decisions, vendor management, and documentation.
- Systems Administrator: manages servers, operating systems, storage, and user accounts
- Network Administrator: manages switches, routers, firewalls, VPNs, and network monitoring
- Cloud Systems Administrator: manages cloud infrastructure on AWS, Azure, or GCP alongside on-premises systems
- Security Administrator: manages access controls, patch cycles, and security tooling
- Network Engineer: designs and implements network architecture, often a senior progression from administrator
- Infrastructure Engineer: owns the full stack from physical hardware through virtualisation and cloud
Core Skills and Tools
Entry to the field typically requires a bachelor's degree in a field related to computer or information science [18]. Core technical skills include TCP/IP networking, routing and switching, firewall management, Windows and Linux server administration, virtualisation (VMware, Hyper-V), and increasingly cloud platforms. Certifications that employers recognise include CompTIA Network+, CompTIA Security+, Cisco CCNA, Microsoft Azure Administrator (AZ-104), and AWS Certified SysOps Administrator. The 2024 Skillsoft IT Skills and Salary Report listed an average US network administrator salary of USD 93,126, with engineers and architects clearing six figures, underscoring the value of advancing beyond the administrator title [11].

Labour Market, Salaries, and the Skills Gap
The three fields sit at different points on the labour market curve. Computer and information systems managers, the senior end of the ITSM and enterprise operations spectrum, are in strong demand: employment is projected to grow 16 percent from 2025 to 2035, with 53,500 annual openings and a median wage of USD 175,140 [2]. Computer systems analysts, who often bridge ITSM and enterprise operations, held 544,400 jobs in 2025 with a median wage of USD 105,850 and projected growth of 8 percent through 2035 [8].
Network and systems administration tells a more nuanced story. The headline 4 percent projected decline reflects the consolidation of traditional administrator roles as cloud platforms automate routine tasks [10]. But the underlying demand for infrastructure skills has not disappeared; it has shifted. Administrators who develop cloud, security, and automation skills move into cloud networking, security engineering, and DevOps roles where demand is growing. The BLS projects that the strong and increasing demand for IT solutions, including AI-based systems, will boost demand for computer and mathematical occupations overall, with five of the 15 fastest-growing US occupations in this group [6].
The skills gap is real and measurable. Research cited in a 2025 state-of-the-IT-market analysis found that IT operations and support was the second most acute skill shortage area among tech leaders, cited by 39 percent of respondents, behind only AI and machine learning at 44 percent [3]. This gap creates opportunity for practitioners who invest in structured learning rather than relying solely on on-the-job experience.
The free first section of IT Service Management and Enterprise Operations offers a no-commitment way to assess whether the enterprise operations curriculum matches your current experience before enrolling.
Frameworks, Standards, and Certifications That Matter
ITSM practice is governed by a mature set of frameworks and standards. ITIL 4 is the most widely adopted, with a structured certification path that runs from Foundation through Managing Professional, Strategic Leader, Practice Manager, and Master. The Foundation level is the standard entry credential; Managing Professional covers the skills needed to lead in ITSM. The ITIL 4 Master designation is the highest achievement in the scheme, requiring completion of both Managing Professional and Strategic Leader designations and demonstrating application in real-world ITSM environments.
Beyond ITIL, practitioners encounter ISO/IEC 20000 (the international standard for IT service management), COBIT (for IT governance), and increasingly DevOps and site reliability engineering (SRE) practices as organisations integrate development and operations. For network and systems administration, the relevant standards include IEEE networking standards, NIST cybersecurity frameworks, and vendor-specific certification programmes from Cisco, Microsoft, and Amazon Web Services.
- ITIL 4 Foundation: entry-level ITSM credential, covers service value system and key practices
- ITIL 4 Managing Professional: covers high-velocity IT, direct, plan and improve, and create, deliver and support
- ITIL 4 Strategic Leader: covers digital and IT strategy and direct, plan and improve
- ISO/IEC 20000: international standard for IT service management systems
- CompTIA Network+: vendor-neutral networking fundamentals credential
- Cisco CCNA: entry-level networking credential covering routing, switching, and security basics
- Microsoft AZ-104: Azure Administrator credential for cloud infrastructure management
- AWS Certified SysOps Administrator: cloud operations credential for AWS environments
Original analysis
vaayaa analysis: Wage premium and growth rate comparison across the three fields
- Step 1: Identify the BLS median wage for each field. Computer and IS managers (senior ITSM and enterprise operations): USD 175,140. Computer systems analysts (ITSM practitioners): USD 105,850. Network and systems administrators: USD 99,130. All-occupations median: USD 50,980. Source: BLS OOH, May 2025 [2][8][10].
- Step 2: Calculate the wage premium over the all-occupations median for each field. Computer and IS managers: (175,140 - 50,980) / 50,980 = 243.5% premium. Computer systems analysts: (105,850 - 50,980) / 50,980 = 107.6% premium. Network and systems administrators: (99,130 - 50,980) / 50,980 = 94.4% premium.
- Step 3: Compare projected employment growth rates. Computer and IS managers: +16% (2025-2035). Computer systems analysts: +8% (2025-2035). Network and systems administrators: -4% (2025-2035). All-occupations average: +3% (2025-2035). Source: BLS OOH [2][8][10].
- Step 4: Combine wage premium and growth rate into a simple opportunity index. Multiply the wage premium percentage by the growth rate (using 1 for flat, treating negative as a penalty). Computer and IS managers: 243.5 x 16 = 3,896. Computer systems analysts: 107.6 x 8 = 861. Network and systems administrators: 94.4 x (-4) = -378 (contraction signal).
- Step 5: Interpret. The analysis shows that moving up the ITSM and enterprise operations ladder, from systems analyst to IS manager, produces a disproportionate jump in both wage premium and growth opportunity. Network administration remains well-paid relative to the economy but faces structural contraction, making lateral moves into cloud or security administration the logical career hedge.
Senior ITSM and enterprise operations management roles offer a wage premium of 243 percent over the all-occupations median and a projected growth rate of 16 percent, making them the strongest combination of current pay and future demand among the three fields. Network and systems administration offers a 94 percent wage premium but faces a projected 4 percent employment decline, meaning practitioners in that field face the clearest incentive to develop adjacent skills in cloud infrastructure, security, or ITSM process management to protect long-term career value.

- Year 5-8: Accumulate 5+ years of relevant experience. Move to IT Operations Manager or Service Delivery Manager. BLS median for computer and IS managers: USD 175,140 [2].
- Total certification investment: approximately USD 1,850 (Network+, ITIL Foundation, ITIL Managing Professional modules). Total time: 5 to 8 years from entry-level support to operations manager.
A practitioner who follows this pathway can move from an entry salary of approximately USD 50,000 to a median operations manager salary of USD 175,140 in 5 to 8 years, with a total certification spend of under USD 2,000. The wage increase from entry to manager level represents a gain of approximately USD 125,000 per year at median, making the certification investment highly cost-effective. These figures use BLS median wages and PeopleCert published exam prices; individual outcomes will vary by location, employer, and performance.
Practical Checklist: Assessing Your Readiness to Enter or Advance in These Fields
- Confirm your current role: are you in hands-on administration, process-focused ITSM, or a hybrid operations role? This determines which skills gap to close first.
- Review the BLS Occupational Outlook Handbook entries for your target role to check median wage, entry requirements, and projected growth before committing to a learning path.
- If you are in network or systems administration, identify whether your skills include at least one cloud platform (AWS, Azure, or GCP) and one security domain, as these are the growth areas adjacent to traditional administration.
- If you are targeting ITSM or enterprise operations, check whether your organisation uses ITIL-aligned processes and which ITSM platform it runs, then align your learning to that toolset.
- Earn ITIL 4 Foundation before applying for any ITSM-titled role; most job descriptions list it as a requirement or strong preference.
- Build a portfolio of documented process improvements, incident reports, or infrastructure projects you have led or contributed to; ITSM and operations hiring managers value evidence of structured thinking over credentials alone.
- Identify a mentor or peer in your target role and ask for a realistic account of day-to-day work, including the parts that are not in the job description.
- Set a 12-month learning goal with a specific certification target, a salary benchmark from BLS data, and a date to reassess progress.
Frequently asked questions
Is network administration a dying career?
The BLS projects a 4 percent employment decline for network and computer systems administrators from 2025 to 2035, driven by cloud consolidation and automation [10]. However, 13,400 annual openings are still expected from retirements and role transitions [10]. Administrators who develop cloud networking, security, or ITSM skills are well positioned to move into adjacent roles where demand is growing. The title may shrink; the underlying skill set remains valuable.
What is the difference between ITSM and IT operations?
ITSM is the framework of processes and practices used to design, deliver, and manage IT services. IT operations is the function that executes those processes day to day, managing infrastructure, monitoring services, and responding to incidents. In small organisations the two overlap heavily. In large enterprises, ITSM defines the rules and IT operations runs the game, with enterprise operations integrating both into a coherent management function aligned to business objectives.
Do I need a degree to work in these fields?
The BLS lists a bachelor's degree as the typical entry-level education for both network and systems administrators and computer and information systems managers [2][18]. In practice, many employers accept equivalent experience combined with industry certifications such as CompTIA Network+, Cisco CCNA, or ITIL 4 Foundation. Certifications are particularly important in ITSM roles, where the ITIL framework is the recognised standard of professional knowledge.
Which field pays the most?
Senior ITSM and enterprise operations roles pay the most. The BLS reported a median annual wage of USD 175,140 for computer and information systems managers in May 2025, compared with USD 105,850 for computer systems analysts and USD 99,130 for network and systems administrators [2][8][10]. All three fields pay well above the all-occupations US median of USD 50,980 [2]. Pay increases significantly with experience, certifications, and movement into management.
What is ITIL 4 and do I need it?
ITIL 4 is the current version of the Information Technology Infrastructure Library, the most widely adopted framework for IT service management. It organises ITSM practice around a service value chain and a set of management practices. ITIL 4 Foundation is the standard entry credential and is listed as a requirement or preference in most ITSM job descriptions. The certification ladder runs from Foundation through Managing Professional, Strategic Leader, Practice Manager, and Master.
How long does it take to move from help desk to IT operations manager?
Based on BLS entry requirements and typical career progression, the journey from IT support technician to IT operations manager takes roughly 5 to 8 years. The BLS lists 5 or more years of related experience as the typical requirement for computer and information systems managers [2]. The worked example in this discourse estimates a total certification investment of under USD 2,000 for the credentials needed along that path, making structured learning one of the most cost-effective career investments available.
Is cloud computing replacing network administration?
Cloud computing is reshaping rather than eliminating network administration. Routine tasks such as provisioning physical hardware and managing on-premises switches are declining as organisations move workloads to cloud providers. However, cloud environments still require network design, security configuration, and performance management. Administrators who develop skills in cloud networking (AWS VPC, Azure Virtual Network), software-defined networking, and security are moving into cloud infrastructure and network engineering roles where demand is growing [11].
Can someone from a non-IT background enter these fields?
Yes, particularly in ITSM. The process and communication skills required for service desk, incident management, and service delivery roles transfer well from backgrounds in customer service, project management, healthcare administration, and finance. The technical barrier is lower in ITSM than in network administration. Starting with ITIL 4 Foundation and an entry-level service desk role is a practical route for career changers. Network and systems administration requires more technical groundwork, typically starting with CompTIA A+ or Network+ before moving into hands-on roles.
Conclusion
IT service management, enterprise operations, and network and systems administration are three distinct but deeply connected disciplines. ITSM provides the process framework, enterprise operations provides the strategic integration, and network and systems administration provides the infrastructure foundation. Together they represent the operational backbone of every organisation that depends on technology, which in 2026 means every organisation of any scale.
The labour market data tells a clear story: senior ITSM and enterprise operations roles offer strong growth and high wages, with computer and information systems managers earning a median of USD 175,140 and employment projected to grow 16 percent through 2035 [2]. Network and systems administration remains well-paid but faces structural contraction, making skills diversification into cloud, security, or ITSM process management the logical next step for practitioners in that field [10]. For anyone deciding what to learn, the direction of travel is clear: build infrastructure skills first, then layer process and management knowledge on top, and the career ceiling rises substantially.
