Well, to start, serverless, or serverless computing , doesn’t really mean there aren’t servers involved, because there are, rather it refers to the fact that the responsibility of having to manage, scale, provision, maintain, etc., Applications that are running continuously on a dedicated server aren’t as impacted by latency issues.

The carbon footprint of a large rack mounted server is order-of-magnitude a ton of carbon a year. A rough guide if you don’t have any better data is that with no traffic to a system it will be 10% utilization and use 30% of peak power, 25% utilization uses 50% of peak power, and at 50% utilization it uses 75% of peak power.

Before GraphQL: Monolithic Falcor API implemented and maintained by the API Team Before moving to GraphQL, our API layer consisted of a monolithic server built with Falcor. A single API team maintained both the Java implementation of the Falcor framework and the API Server. To launch Phase 1 safely, we used AB Testing.

Thanks to its reliable performance, extensive documentation and dedicated user community, PHP is one of the preferred server-side scripting language of many web developers. AWS Cloud 9 AWS Cloud 9 is ideal for developing PHP applications completely in the cloud. Below is a run down of a few useful PHP tools for developers.

Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side. This server is spending about a third of its CPU cycles just checking the time! Other EC2 instance types, such as C5 or M5, use the AWS Nitro Hypervisor.

Oracle VM Server is based on Xen. Both Xen and KVM have had many performance and security improvements, and workloads can now be tuned to run at almost bare metal speeds (say, a 3% loss or less). Outside of EC2, many other providers are deploying on KVM. I also wrote and published an entertaining SMF manifest that played music.

To this end, we developed a Rapid Event Notification System (RENO) to support use cases that require server initiated communication with devices in a scalable and extensible manner. We thus assigned a priority to each use case and sharded event traffic by routing to priority-specific queues and the corresponding event processing clusters.

A brief history of IPC at Netflix Netflix was early to the cloud, particularly for large-scale companies: we began the migration in 2008, and by 2010, Netflix streaming was fully run on AWS. The ability to run in a degraded but available state during an outage is still a marked improvement over completely stopping traffic flow.

As we began growing the AWS business, we realized that external customers might find our Dynamo database just as useful as we found it within Amazon.com. So, we set out to build a fully hosted AWS database service based upon the original Dynamo design. Durable and Highly-Available – DynamoDB maintains data durability and 99.99

Blocking write traffic by locking tables. Writing events to any output.
