Amazon EC2 Auto Scaling DynamoDB & EC2 Management

Amazon EC2 Auto Scaling automatically adjusts your DynamoDB and EC2 resources for reliable performance and cost-effective management.

Why AWS Auto Scaling?

In order to guarantee consistent, reliable performance at the lowest feasible cost, AWS Auto Scaling keeps an eye on your apps and automatically modifies capacity. Setting up application scaling for numerous resources across numerous services is simple and takes only a few minutes using AWS Auto Scaling. You may create scaling plans for resources like Amazon EC2 instances and Spot Fleets, Amazon ECS tasks, Amazon DynamoDB tables and indexes, and Amazon Aurora Replicas using the service’s straightforward yet robust user interface. Amazon Auto Scaling simplifies scaling by offering suggestions that let you balance costs and performance.

You may now scale more resources for other AWS services by combining Amazon EC2 Auto Scaling with AWS Auto Scaling if you’re already using it to dynamically scale your Amazon EC2 instances. Your apps will always have the appropriate resources available when they need them with AWS Auto Scaling.

The AWS Management Console, Command Line Interface (CLI), or SDK make it simple to begin using AWS Auto Scaling. There is no extra cost for AWS Auto Scaling. You simply have to pay for Amazon CloudWatch monitoring fees and the AWS resources required to run your apps.

Advantages

Quick setup scaling

Using a single, user-friendly interface, AWS Auto Scaling enables you to establish target utilisation levels for numerous resources. Without having to switch between terminals, you can easily view the average usage of all of your scalable resources. For instance, you can use AWS Auto Scaling to control resource provisioning for all of the Amazon EC2 Auto Scaling groups and database tables in your application if it makes use of Amazon EC2 and Amazon DynamoDB.

Make smart scaling decisions

You can create scaling plans using AWS Auto Scaling that automate how collections of various resources react to variations in demand. Costs, availability, or a combination of the two can be optimised. AWS Auto Scaling establishes goals for you based on your preferences and automatically generates all scaling policies. As demand changes, AWS Auto Scaling keeps an eye on your application and instantly adds or subtracts capacity from your resource groups.

Automatically maintain performance

AWS Auto Scaling can optimise application performance and availability for intermittent, inconsistent, or variable workloads. AWS Auto Scaling monitors app performance to meet your needs. As demand rises, AWS Auto Scaling dynamically expands restricted resources to maintain service quality.

Pay only what you need

When using AWS services, AWS Auto Scaling can help you maximise utilisation and reduce costs so you only pay for the resources you truly require. To prevent overspending, AWS Auto Scaling will immediately eliminate any surplus resource capacity when demand declines. You may optimise the expenses of your AWS environment by using AWS Auto Scaling, which is free to utilise.

Features of AWS Auto Scaling

Unified scaling

All of the scalable resources that drive your application may be automatically scaled using AWS Auto Scaling from a single, consistent interface, including:

  • Amazon EC2: In an Amazon Amazon EC2 Auto Scaling group, start or stop Amazon EC2 instances.
  • Amazon EC2 Spot Fleets: Use an Amazon EC2 Spot Fleet to start or stop instances, or have instances automatically restarted when they are halted due to capacity or cost issues.
  • Amazon ECS: Respond to changes in load by adjusting the ECS service desired count up or down.
  • Amazon DynamoDB: To boost its provisioned read and write capacity to manage abrupt spikes in traffic without throttling, enable a DynamoDB table or a global secondary index.
  • Amazon Aurora: To manage unexpected spikes in the number of active connections or workload, dynamically modify the number of Aurora Read Replicas created for an Aurora DB cluster.

Automatic resource discovery

Instead of requiring you to explicitly identify each scalable cloud resource through a separate service interface, AWS Auto Scaling scans your environment and automatically finds the resources that underpin your application.

Built-in scaling strategies

You can choose from three pre-established optimisation options with AWS Auto Scaling that are intended to maximise performance, minimise expenses, or balance the two. You can establish your own goals for resource usage if you’d like. AWS Auto Scaling will develop the scaling policies for each of your resources based on the scaling approach you have chosen.

Scaling Predictively

In order to provision the appropriate number of EC2 instances ahead of anticipated changes, predictive scaling forecasts future traffic, including spikes that occur often. The machine learning algorithms used by Predictive Scaling automatically modify their projections when they identify changes in daily and weekly patterns. This makes Auto Scaling easier to set up and use by eliminating the need for manual parameter adjustments over time. Predictive scaling combined with auto scaling makes capacity provisioning quicker, easier, and more precise, which lowers costs and improves application responsiveness.

Fully-managed

Using the scaling method you have chosen, AWS Auto Scaling automatically establishes target monitoring scaling policies for every resource in your scaling plan, setting the target values for every metric. Additionally, Amazon CloudWatch alarms that initiate scaling changes for every resource are generated and managed by AWS Auto Scaling.

Smart scaling rules

To keep your metrics on track, AWS Auto Scaling continuously determines the proper scaling adjustments and instantly adds or removes capacity as necessary. Self-optimizing AWS target tracking scaling policies minimise resource capacity changes by learning your actual load patterns. As a result, scalability is more intelligent and seamless, and you only pay for the resources you truly use.
