AWS Lambda Integration with Amazon DynamoDB Streams

2021-05-03T13:23:37+00:00

Amazon DynamoDB is integrated with AWS Lambda so that you can create triggers, which are pieces of code that automatically respond to events in DynamoDB Streams. With triggers, you can build applications that react to data modifications in DynamoDB tables. After you enable DynamoDB Streams on a table, associate the DynamoDB table with a Lambda function. AWS Lambda polls the stream and invokes your Lambda function synchronously when it detects new stream records.  Configure the StreamSpecification you want for your DynamoDB Streams: StreamEnabled (Boolean) - indicates whether DynamoDB Streams is enabled (true) or disabled (false) on the table. StreamViewType (string) [...]

Kinesis Scaling, Resharding and Parallel Processing

2023-03-20T03:29:22+00:00

Kinesis Resharding enables you to increase or decrease the number of shards in a stream in order to adapt to changes in the rate of data flowing through the stream. Resharding is always pairwise. You cannot split into more than two shards in a single operation, and you cannot merge more than two shards in a single operation. The Kinesis Client Library (KCL) tracks the shards in the stream using an Amazon DynamoDB table, and adapts to changes in the number of shards that result from resharding. When new shards are created as a result of resharding, the KCL discovers [...]

DynamoDB Scan vs Query

2023-01-30T13:33:00+00:00

Scan The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. The total number of scanned items has a maximum size limit of 1 MB. Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation. Scan uses eventually consistent reads when accessing the data in a table; therefore, the result set might not include the changes to data in the table immediately before the operation began. If you need a consistent copy of the data, as [...]

ECS Task Placement Strategies

2023-02-17T06:36:28+00:00

A task placement strategy is an algorithm for selecting instances for task placement or tasks for termination. When a task that uses the EC2 launch type is launched, Amazon ECS must determine where to place the task based on the requirements specified in the task definition, such as CPU and memory. Similarly, when you scale down the task count, Amazon ECS must determine which tasks to terminate.  A task placement constraint is a rule that is considered during task placement. You can use constraints to place tasks based on Availability Zone or instance type.  You can also associate attributes, which [...]

AWS Serverless Application Model (SAM)

2023-06-06T07:36:32+00:00

AWS Serverless Application Model (SAM) Cheat Sheet An open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings.  You create a JSON or YAML configuration template to model your applications.  During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax. Any resource that you can declare in an AWS CloudFormation template you can also declare in an AWS SAM template. The SAM CLI provides a Lambda-like execution environment that lets you locally build, test, and debug applications defined by SAM templates. You can also use the SAM CLI [...]

AWS Migration Strategies – The 7 R’s

2024-01-18T07:24:30+00:00

The Seven Common Migration Strategies (7 R’s) Rehost (“lift and shift”) Move applications to AWS without changes. In large-scale, legacy migrations, organizations are looking to move quickly to meet business objectives. Applications may become easier to re-architect once they are already running in the cloud. This happens because the hard part, which is migrating the application, data, and traffic, has already been accomplished. Replatform (“lift, tinker and shift”) You are making a few cloud optimizations in order to achieve some tangible benefit without changing the core architecture of the application. Replatforming Tools Amazon Relational Database Service (RDS) for relational databases [...]
