Azure Autoscale vs. AWS Auto Scaling

By Brian Garoutte

Autoscaling is a systematic method in cloud computing that enables organizations to automate the number of computational resources according to active users’ demands. Systems will automatically set aside the right amount of resources at different periods based on defined scaling rules. 

There are two major ways to autoscale: vertically and horizontally. Vertical scaling involves scaling resources up and down, which changes their capacity. Horizontal scaling, also known as in-and-out scaling, controls the instances of a resource.

Through autoscaling, organizations can optimize steady and predictable server performance at the lowest cost. AWS and Azure are two of the biggest names in cloud computing that offer built-in autoscaling capabilities — providing an excellent reason for cloud migration over on-premise solutions. 

Understanding AWS Auto Scaling

The AWS autoscaling feature is free to use and conveniently set up with the AWS Management Console, CLI (command-line interface), or SDK (software development kit). Users only need to pay additional fees for used resources and CloudWatch monitoring, which provides data and actionable insights on AWS.

Through the AWS autoscaling feature, users can look forward to scaling multiple resources across servers within a short time frame. 

Advantages:
#1. Provides autoscaling groups, which enable users to categorize instances into logical groupings for more convenient scaling and management.
#2. Enhanced fault tolerance, driving quick response in detecting and replacing faulty instances.
#3. Runs predictive scaling that applies machine learning technology in estimating expected traffic for proactive provision of compute. 

Downside:
The system’s cooldown feature may cause inaccuracies without proper precautions. Short cooldowns may result in “over-scaling” or “under-scaling.” Users need to ensure that a cooldown period equals the time taken for a metric to fulfill a scaling event.  

Understanding Azure Autoscale 

Microsoft Azure offers a built-in autoscale feature that enables users to schedule system alerts based on any defined metric such as CPU status, user response rates, and event triggers. Azure users can benefit from key performance metrics that moderate system performances for optimal results. 

Advantages:
#1. Responsive scaling allows users to scale automatically without manual administration.
#2. Customized metrics provide improved flexibility in autoscaling. Users may define beyond resource metrics by applying preset instances.
#3. Features more availability zones (AZs) than the AWS infrastructure, reducing the likelihood of server downtime. 

Downside
There is a required learning curve for other programs (for example, Azure PowerShell).

Both autoscaling services provide businesses with the capabilities to optimize the cost-effectiveness of their servers. Ultimately, the choice lies in individual user needs and workload demands. Complex processes may require a multi-cloud approach. Regardless, a unified automated solution can significantly boost standard autoscaling services. 

Enhancing Azure Autoscaling With MyCloudIT 

While Azure provides convenience and visibility, a next-generation software solution like MyCloudIT can help Azure users simplify and optimize autoscaling savings. MyCloudIT supports users in managing their resources on a granular level with real-time data and enhanced automation. 

Maintain Seamless Autoscaling 
MyCloudIT users can look forward to seamless autoscaling set-ups, with a user-friendly approach that eliminates the need for prior knowledge in Azure PowerShell and CLI. System administrators can get an autoscale system running without downtime. 

Apply Real-time Capabilities 
With MyCloudIT, users gain access to real-time insights on resource management, exceeding the limitations of the Azure Portal. Organizations can enjoy improved visibility and configuration control to max out autoscale savings. 

Generate Insightful Reports
MyCloudIT’s intuitive interface enables users to generate routine (weekly, monthly, and annual) cost-saving reports for a dynamic autoscaling strategy based on the latest system data. The platform’s detailed reports include historical data and estimates to provide users with a complete view of processes and in-use metrics.
