AWS Lambda - Run Code in the Cloud We want to make it even easier for you to build applications that run in the Cloud. We want you to be able to focus on your code, and to work within a cloud-centric environment where scalability, reliability, and runtime efficiency are all high enough to be simply taken for granted! Today we are launching a preview of AWS Lambda, a brand-new way to build and run applications in the cloud, one that lets you take advantage of your existing programming skills and your knowledge of AWS. Lambda is a zero-administration compute platform. Let's dig in! Lambda Concepts The most important Lambda concept is the , or function for short. You upload your code and then specify context information to AWS Lambda to create a function. After uploading, you associate your function with specific AWS resources (a particular S3 bucket, DynamoDB table, or Kinesis stream). When a resource changes, Lambda will execute any functions that are associated with it. I simply click on Create Function to get started.
Sourcegraph Replicant Architecture - Flynn The Flynn architecture is designed to be simple and understandable. Most of the components of Flynn are no different than the services or applications that are deployed on top of Flynn. This is because the primary object in the system is the container and nearly everything runs in a container. For ease of understanding the significance of the components, Flynn is broken down into two layers. Layer 0, is the core of Flynn. Layer 1 is where most of what we consider Flynn to be exists. At a high level, here are the concerns of each layer, which map to basic components. § Layer 0 Distributed configuration / coordinationJob schedulingService discoveryHost abstraction § Layer 1 Management API / clientGit receiverHeroku BuildpacksDatastore appliancesRouting § Layer 0 Layer 0 provides a lower level platform, useful even outside of Flynn, that provides a solid abstraction between a cluster of hosts and containerized processes. It focuses on containers. § Distributed configuration / coordination
A new image format for the Web - WebP WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index. Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. Lossy, lossless and transparency are all supported in animated WebP images, which can provide reduced sizes compared to GIF and APNG. More Info for Webmasters How WebP Works Lossy WebP compression uses predictive coding to encode an image, the same method used by the VP8 video codec to compress keyframes in videos. Lossless WebP compression uses already seen image fragments in order to exactly reconstruct new pixels. WebP Compression Techniques in Detail WebP Support WebP Converter Download
