Imagine you’re a spectator at an outdoor stadium watching a football game or enjoying a concert. An unexpected, severe storm hits, and you have to be rushed out in a safe and secure manner.

Minutes later, you hear an announcement that the event is canceled, and you’re sandwiched in with thousands of others – everyone wanting to get to the same mass transportation services as quickly as possible.

This sounds like a potentially bad scenario, but with the right 5G mobile technology, the stadium can easily transmit local content to the public. In real-time, they can communicate the safest and most efficient steps to get people where they need to go and make sure they all followed their individual paths – all thanks to multi-access edge computing (MEC) — also known as mobile edge computing. 

What is multi-access edge computing (MEC)?

MEC can be defined as cloud services running at the edge of a network and performing specific tasks — in real- or near-real-time — that would otherwise be processed in centralized core or cloud infrastructures. MEC moves computing power closer to the end-user in order to enable applications and services requiring unique connectivity characteristics such as ultra-low latency. It allows content, services and applications to be accelerated by increasing their responsiveness.

Characteristics of MEC

  • Close proximity: Being close to the source of information, edge captures key information for analytics and processing, thereby reducing the need to backhaul data to core locations.
  • Real-time:  Applications that benefit from MEC are ones that require near-real or real-time decision processing and outcomes.
  • Low latency: Typically characterized by latency of under 20 milliseconds. This provides faster response and improved user experience.
  • Continuous operations: Edge applications are localized, meaning they can run independently from the rest of the network — even autonomously if disconnected from the core.
  • Interoperability: MEC does not require adoption or migration of applications to the new environment, which makes development and deployment more efficient.

For the Communications Service Provider (CSP), new applications that are aware of the local context in which they operate (RAN and vRAN conditions, locality, subscriber information, etc.) can open up entire new service categories. For example, mobile operators that are now introducing 5G can leverage the same cloud native infrastructure to run both MEC and vRANs on the same COTs hardware.  

Placing relevant applications on or near the base station not only offers advantages to consumer and enterprise end users, it also reduces the volume of traffic offloaded to the core network and minimizes operational costs (OPEX) and helps to address security and data governance issues

Finally, MEC means being able to rapidly deploy new services for consumer and enterprise business segments, which can help them differentiate their service portfolio and increase new revenue streams.

The history of the central processing unit (CPU)

10 min read - The central processing unit (CPU) is the computer’s brain. It handles the assignment and processing of tasks, in addition to functions that make a computer run. There’s no way to overstate the importance of the CPU to computing. Virtually all computer systems contain, at the least, some type of basic CPU. Regardless of whether they’re used in personal computers (PCs), laptops, tablets, smartphones or even in supercomputers whose output is so strong it must be measured in floating-point operations per…

A clear path to value: Overcome challenges on your FinOps journey 

3 min read - In recent years, cloud adoption services have accelerated, with companies increasingly moving from traditional on-premises hosting to public cloud solutions. However, the rise of hybrid and multi-cloud patterns has led to challenges in optimizing value and controlling cloud expenditure, resulting in a shift from capital to operational expenses.   According to a Gartner report, cloud operational expenses are expected to surpass traditional IT spending, reflecting the ongoing transformation in expenditure patterns by 2025. FinOps is an evolving cloud financial management discipline…

IBM Power8 end of service: What are my options?

3 min read - IBM Power8® generation of IBM Power Systems was introduced ten years ago and it is now time to retire that generation. The end-of-service (EoS) support for the entire IBM Power8 server line is scheduled for this year, commencing in March 2024 and concluding in October 2024. EoS dates vary by model: 31 March 2024: maintenance expires for Power Systems S812LC, S822, S822L, 822LC, 824 and 824L. 31 May 2024: maintenance expires for Power Systems S812L, S814 and 822LC. 31 October…
