Worldwide IT Services Revenue Exceeded $1 Trillion

More CIOs and CTOs seek vendor expertise as demand for digital transformation guidance grows. Worldwide revenues for IT Services and Business Services totaled $513 billion in the second half of 2018 (2H18) -- that's an increase of 4.5 percent year-over-year, according to the latest study by International Data Corporation (IDC).

For the entire year, worldwide IT services revenues crossed the $1 trillion mark in 2018. Annual growth accelerated slightly to 4.3 percent. This largely reflects overall healthy corporate IT spending sustained by large enterprises' cautious yet optimistic business outlook.

"Steady growth in the services markets are driven by continued demand for digital solutions across the regions with the Americas continuing to contribute to the bulk of the revenue growth," said Lisa Nagamine, research manager at IDC.

IT Services Market Development

Looking at different services markets, project-oriented revenues (i.e. consulting, integration, application development, etc.) continued to outpace outsourcing and support & training. They grew by 6.4 percent year-over-year in 2H18 to $194 billion and 5.8 percent to $380 billion for the entire year.

The growth was led largely by business consulting and application development markets. Business consulting grew 9.1 percent to $63 billion in 2H18 and 8.3 percent to $123 billion for the year. Custom application development (CAD) grew 8.3 percent to almost $24 billion in 2H18 and 7.5 percent to $46 billion for 2018 (compared with only 5.1 percent in 2017).

Market growth was largely due to strong results in the United States. As traditional U.S. enterprises and government agencies continue to tackle and adopt digital transformation, strategic consulting remains critical in larger projects. Digital transformation is also driving up new application development work.

In managed services, revenues grew 3.8 percent to $240 million in 2H18 and 3.6 percent to $473 million for 2018, which is on par with real worldwide GDP growth. Application-related managed services revenues (hosted and on-premise application management) outpaced infrastructure and business process outsourcing (BPO), growing by 5.8 percent to $41 billion in 2H18 and 5.6 percent to $80 billion for 2018.

Like application project work (CAD), application outsourcing serves as a vehicle for buyers to access new app skills (i.e. cloud, analytics, machine learning, etc.), as well as modernizing legacy apps via external providers. IDC expects application-related managed services to continue to outperform other outsourcing segments.

According to the IDC assessment, IT Outsourcing (ITO) continued to decline due to flat or negative growth in the mature geographic markets. This was offset somewhat by moderate growth in horizontal business process outsourcing (BPO).

On a geographic basis, the United States, the largest services market, grew by 4.8 percent to $233 million in 2H18 and 4.6 percent to $459 million for 2018, a moderate acceleration. Strong economic growth in the U.S. despite policy uncertainties, coupled with moderate but steady government spending increases, have kept both corporate and government IT spending robust.

Western Europe, the second largest market, grew by almost 3 percent to $266 billion for 2018, much slower than the U.S. but in-line with IDC's previous estimate and more than twice as fast as real GDP growth for the region. This was driven largely more application-related activities in the region, notably CAD and application outsourcing.

Asia-Pacific (excluding Japan) growth cooled slightly to 6.2 percent with revenues of $110 billion, partially reflecting economic angst over the impending trade war between the U.S. and China, and the economic slowdown in key mature markets (i.e. Australia/New Zealand, South Korea).

Japan enjoyed a slight growth uptick, as business results from the major Japanese services vendors posted slightly higher than expected in 2H18, mainly due to continuing demands for system renewal.

Outlook for IT Services Growth in Emerging Markets

Other emerging markets in the region continued to show robust growth (i.e. India, the Philippines, Indonesia, Vietnam, etc.) However, their impact on growth was limited by their size. Overall growth for the entire APeJ region remains at around 5 percent for 2018.

In other emerging markets, both Latin America and Central & Eastern Europe (CEE) saw faster growth in 2018 than the previous year. Except for Venezuela and Argentina, and to some degree Colombia, major Latin American markets are in economic recovery, which drove both corporate and government IT spending.

All foundation markets showed better growth last year. In CEE, most major geographic markets grew between 6 percent and 15 percent, mainly boosted by dynamic economic growth and increased tax revenues. However, in sheer revenue size, CEE is still the smallest geographic market.

Anywhere, Anytime Workplace Demand for SASE

The ongoing adoption of flexible working models within the enterprise market has significant implications for typical IT organizations that must now support knowledge workers and front-line employees that operate outside the corporate network perimeter. The global COVID-19 pandemic created IT networking and security challenges. The expansion of the distributed workforce, an increasing reliance on cloud computing infrastructure, and the requirement to securely connect online employees -- wherever they choose to work, at any given moment in time. Legacy IT solutions that have rigid network underlays and a requirement for on-premises infrastructure cannot adequately deal with these trends. This 'Anywhere, Anytime Workplace' led to demand for new Secure Access Service Edge (SASE) solutions, with networking and security delivered as-a-service. Anywhere, Anytime Workplace Market Development   Although converging networking and security capabilities offer enterprises a promising solut

The Metaverse Raised Virtual Reality Interest

After years of slow growth and limited use cases, the Virtual Reality (VR) market is now forecast to grow significantly over the next five years. Consumer interest in VR games and media continues to grow after the COVID-19 pandemic accelerated activity. At the same time, the need for employee enablement and immersive content within the enterprise environment remains strong. According to the latest market study by ABI Research, over 90 million Head Mounted Display (HMD) shipments in 2027 will drive total VR market revenues to reach over $95 billion across hardware, software, and services. Virtual Reality Market Development "The virtual reality market is no stranger to false starts, with identifiable efforts in VR dating back to the 1980s and 1990s. While the technology never found purchase results, the increased capability of VR hardware combined with the demand for immersive content in numerous markets, presents a significant opportunity," says Eric Abbruzzese, research direc

Cloud Edge Computing Demand Continues to Grow

Public cloud computing solutions are moving closer to the edge of networks where CIOs and CTOs are hosting new apps. The edge journey is well underway for forward-looking organizations as they seek to connect with customers, improve operational efficiency, and adopt digital business technologies to drive innovation. The latest worldwide market study by International Data Corporation (IDC) found that three-quarters of organizations plan to increase their edge computing spending over the next two years with an average increase of 37 percent. A combination of factors is driving this increased spending at the edge. Cloud Edge Computing Market Development The performance requirements of expanding workloads and new use cases that leverage artificial intelligence (AI) and machine learning (ML) demand greater compute capacity at the edge. In addition, the amount of data being stored in edge locations are rapidly expanding, and organizations plan to keep this data longer. As a result, the numbe
