Auto Scaling (AS)
(AS)
Auto Scaling automatically adjusts compute resources based on scaling policies you define, striking a balance between performance and cost.
Elasticity
Enable your infrastructure to scale up or down automatically based on real-time demand. This elasticity ensures that your applications can handle sudden traffic spikes or unexpected usage patterns without any manual intervention.
High Availability
Your applications are distributed across multiple servers or instances. In the event of a server failure or increased load, the system automatically launches new instances to maintain optimal performance.
Optimize Performance and Cost
Achieve peak performance and cost optimization for your cloud-based applications with our Auto Scaling solution. AS dynamically adjusts your infrastructure based on real-time demand, ensuring optimal resource allocation and eliminating unnecessary expenses.
Why AS?
Reduce Cost
Auto Scaling works with ELB to balance the load among instances in your Auto Scaling groups. It maintains high application availability by adding instances on demand and replacing unhealthy instances with new ones. It supports scheduled, periodic, and alarm scaling policies to help you confidently handle with any changes in workload.
Better User experience.
Lifecycle hooks allow your applications to respond to scaling events in your Auto Scaling groups. Graceful scale-in ensures that running tasks are complete before the instances terminate so services are not interrupted. Any time an instance is launched or terminated in your Auto Scaling groups, you will be notified.
Use Cases
Web Applications
High Performance Computing
Web Applications
Web Applications
During surges in demand, your website may need additional resources to maintain the desired performance. When demand slows and these additional resources are no longer needed, they can be offloaded so you do not need to continue paying for them. With Auto Scaling, you get a scalable architecture that automatically scales up or down to maintain optimum performance at the lowest possible cost, so that your business is prepared for all scenarios.
Advantages
– Fault-Tolerant
Requests are distributed to instances deployed in OREL Cloud to isolate failures by design. You get the reliability of geographic redundancy. Auto Scaling can also detect unhealthy instances and replace them with new ones to help ensure your applications never crash.
– Load Balancing
You can attach a load balancer to your Auto Scaling group to manage incoming requests by optimizing traffic routing so that no one instance is ever overwhelmed.
– Fully Managed
Auto Scaling monitors the health of running instances in real time and automatically manages the launch and removal of instances on your behalf.
High Performance Computing
High-Performance Computing
You can schedule a batch of compute instances to be automatically created for tasks at scheduled time and then have them immediately released when tasks are complete. During the process, the number of compute instances can also be automatically adjusted based on size of the workload over time.
Advantages
– Flexible
You can manually change the size of your Auto Scaling group or configure scheduled, periodic, or alarm-triggered scaling policies to have the group scaled automatically.
– Low Cost
Auto Scaling adds instances only when needed, and can scale across purchase options to optimize performance and cost. You pay only for what you use.
– Varied Specifications
Auto Scaling allows you to deploy compute tasks across multiple instance types to enhance performance.
