IP Multimedia Subsystem (IMS) is about to revolutionize the telecom market. According to ABI Research analyst Ian Cox, "Every Tier 1 service provider in fixed and wireless networks will announce SIP-based services running over IMS in the next six to twelve months." IMS began life as a wireless network architecture for adding IP-based services to existing circuit-switched voice. When Session Initiated Protocol (SIP) was introduced, IMS evolved to an open architecture: operators are not locked into a proprietary solution, nor are point solutions needed for each service. Soon fixed network providers began adapting it to IP networks. IMS allows a single device to use both fixed and wireless networks. IMS will allow many new services, including VoIP, to be offered simultaneously over SIP-enabled networks. Vendors can develop applications and equipment knowing they will be fully interoperable. Services can be tried quickly and discarded if unpopular. A single database holds all subscriber information, lowering operating costs for multiple services.
The worldwide server market has entered a new phase defined almost entirely by artificial intelligence (AI) infrastructure economics rather than traditional enterprise refresh cycles. The latest market data shows robust growth and a structural shift in where value is created, who captures it, and which architectures are setting the pace for the next decade. IDC reports that worldwide server revenue reached a record $112.4 billion in the third quarter of 2025, representing a striking 61 percent year-over-year increase compared to the same quarter in 2024. For context, this means the market is adding tens of billions of dollars in incremental quarterly spend, driven overwhelmingly by AI and accelerated computing requirements. IT Server Market Development Over the first three quarters of 2025, server revenue has already reached $314.2 billion, meaning the market has nearly doubled in size compared to 2024, underscoring how AI buildouts have compressed several years of exp...
