Infrastructure as code vs. platform as code

With infrastructure as code (IaC), you write declarative instructions about compute, storage and network requirements for the infra and execute it. How does this compare to platform as code (PaC) and what did these two concepts develop in response to? In its simplest form, the tech stack of any application has three layers — the infra layer containing bare metal instances, virtual machines, networking, firewall, security etc.; the platform layer with the OS, runtime environment, development tools etc.; and the application layer which, of course, contains your application code and data. A typical operations team works on the provisioning, monitoring and management of the infra and platform layers, in addition to enabling the deployment of code.

The world is ready for 5G. Are you?

Article | June 3, 2021

At last, the wait for 5G is nearly over. As this map shows, coverage is widespread across much of the U.S., in 24 EU countries, and in pockets around the globe. The new wireless standard is worth the wait. Compared to 4G, the new wireless standard can move more data from the edge, with less latency. And connect many more users and devices—an important development given that the IDC estimates 152,000 new Internet of Things (IoT) devices per minute by 2025. Put it together, and 5G is a game-changing backhaul for public networks. (Wi-Fi 6, often mentioned in the same breath as 5G, is generally used for private WANs.

Edge computing environments: what you need to know

Article | June 3, 2021

The saying goes: “If you’re not on the edge, you’re taking up too much space”. And compute itself is now moving to the edge, forcing datacentre operators to wring the last drops of productivity from their infrastructure, ahead of a future supporting multi-sensor internet of things (IoT) devices over 5G for machine learning, and even artificial intelligence (AI). Jennifer Cooke, research director of cloud-to-edge datacentre trends at IDC, says datacentre operators need to start thinking about how many systems they will need to roll out, and the people they will need to support them. “Cost becomes the prohibitive factor,”
