Look inside the black box of AWS API Gateway to understand authorization, method requests and responses, integration requests and responses, VTL templates, and more. AWS API Gateway is an awesome service to use as an HTTP frontend. You can use it for building serverless applications, for integrating with legacy applications, or for proxying HTTP requests […]
In my previous post (Disaster Recovery for Cloud Solutions is Obsolete) I asserted that you should design your cloud architectures for Disaster Tolerance from the start (even if it is counter intuitive to do so by lean principles). I also argued that you should do this because it’s easy if you do it now, and […]
The last time we wrote about how to save AWS costs was at the end of 2015. AWS has changed a lot since then. AWS introduced AMD-powered EC2 instances that are 10% cheaper compared to the Intel-powered Instances. They provide the same resources (CPU, memory, network bandwidth) and run the same AMIs. The following table […]
AWS recently released a new service App Mesh during the 2019 summit which has generated a lot of interest from developers world-wide. This service is a great example of how Amazon is highly customer-focused in delivery of products/features to the market. Besides that, there is no additional charge for using the service!:-) With the advent […]
The idea of a “service mesh” has become increasingly popular over the last couple of years and the number of alternatives available has risen. There are multiple service mesh open-source projects: Istio, Linkerd, Envoy and Conduit which can be deployed on any Kubernetes environment. The AWS App Mesh can be used with microservices running on […]
AWS App Mesh is now generally available and supported for production use. App Mesh is a service mesh that provides application level networking to make it easy for your services to communicate with each other across multiple types of compute infrastructure. App Mesh standardizes how your services communicate, giving you end-to-end visibility and ensuring high-availability […]
Last week we made a fairly quiet (too quiet, in fact) announcement of our plan to slowly and carefully deprecate the path-based access model that is used to specify the address of an object in an S3 bucket. I spent some time talking to the S3 team in order to get a better understanding of […]
While evaluating the performance of a server application, we eventually (and hopefully) run up against the most fundamental constraining factor: the network. Cloud providers tend to offer somewhat handwavy guidance on networking constraints, especially when compared to the exhaustive literature explaining the quotas for RAM, CPU, and I/O. While working on an unrelated stress test […]
The premise behind autoscaling in AWS is simple: you can maximize your ability to handle load spikes and minimize costs if you automatically scale your application out based on metrics like CPU or memory utilization. If you need 100 Docker containers to support your load during the day but only 10 when load is lower […]
Our security culture is one of the things that sets AWS apart. Security is job zero — it is the foundation for all AWS employees and impacts the work we do every day, across the company. And that’s reflected in our services, which undergo exacting internal and external security reviews before being released. From there, […]
