Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. Each dimension has progressed through these stages: 1.

Cloud providers then manage physical hardware, virtual machines, and web server software management. The FaaS model of cloud computing debuted in 2014 with startups like hook.io. Increased availability. FaaS enables developers to create and run a single function in the cloud using a serverless compute model.

Since Kubernetes emerged in 2014, it has become a popular solution for scaling, managing, and automating the deployments of containerized applications in distributed environments. This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure. What is Kubernetes?

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. These VMs are not available in all regions, so you will want to check the availability in the Azure region that you are interested in using. Figure 2: Microsoft Project Olympus.

The main improvement MSLs give is that a program data race will not corrupt the language’s own virtual machine (whereas in C++ a data race is currently all-bets-are-off undefined behavior). As of C++20, I believe we have achieved the “superset,” notably by standardizing span , string_view , concepts, and bounds-aware ranges.

Since its introduction by AWS in 2014, AWS Lambda has revolutionized the compute space and boosted the entire serverless movement. To handle N parallel requests, N Lambda instances need to be available, and AWS will spin up up to 1000 such instances automatically to handle 1000 parallel requests. The virtual CPU is turned off.
