AWS Step Functions


AWS Step Functions AWS Step Functions is a web service that provides serverless orchestration for modern applications. It enables you to coordinate the components of distributed applications and microservices using visual workflows. Concepts Step Functions is based on the concepts of tasks and state machines. A task performs work by using an activity or an AWS Lambda function, or by passing parameters to the API actions of other services. A finite state machine can express an algorithm as a number of states, their relationships, and their input and output. You define state machines using the JSON-based Amazon States Language. A [...]

VPC Peering


VPC Peering A networking connection between two VPCs that enables you to route traffic between them privately using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region (also called Inter-Region VPC Peering). A VPC peering connection is neither a gateway nor a AWS Site-to-Site VPN connection, and does not rely on a separate piece of physical hardware. There is [...]

AWS CodeBuild


AWS CodeBuild A fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. Concepts A build project defines how CodeBuild will run a build. It includes information such as where to get the source code, which build environment to use, the build commands to run, and where to store the build output. A build environment is the combination of operating system, programming language runtime, and tools used by CodeBuild to run a build. The build specification is a YAML file that lets you choose the commands to run at each [...]

AWS CodePipeline


AWS CodePipeline A fully managed continuous delivery service that helps you automate your release pipelines for application and infrastructure updates. You can easily integrate AWS CodePipeline with third-party services such as GitHub or with your own custom plugin. Concepts A pipeline defines your release process workflow, and describes how a new code change progresses through your release process. A pipeline comprises a series of stages (e.g., build, test, and deploy), which act as logical divisions in your workflow. Each stage is made up of a sequence of actions, which are tasks such as building code or deploying to test environments. [...]

S3 Transfer Acceleration vs Direct Connect vs VPN vs Snowball vs Snowmobile


S3 Transfer Acceleration vs Direct Connect vs VPN vs Snowball vs Snowmobile   S3 Transfer Acceleration (TA) Amazon S3 Transfer Acceleration makes public Internet transfers to S3 faster, as it leverages Amazon CloudFront’s globally distributed AWS Edge Locations. There is no guarantee that you will experience increased transfer speeds. If S3 Transfer Acceleration is not likely to be faster than a regular S3 transfer of the same object to the same destination AWS Region, AWS will not charge for the use of S3 TA for that transfer. This is not the best transfer service to use if transfer disruption is [...]
