How to Boost Cloud Scalability | 3 Best Ways

Deploying in the Amazon cloud is touted as a great way to achieve high scalability while paying only for the computing power you use. How do you get the best scalability from the technology?

In this article, we have explained three ways to boost your cloud scalability. Let’s explore them below.

3 Ways to Boost Cloud Scalability 

Here are the 3 ways to boost cloud scalability:

1. Use Auto-scaling

Auto-scaling is a unique feature of cloud computing and Amazon’s EC2 offering. Setup a load balancer and a couple of webservers for your application as you normally would.

Design your webserver based on a template AMI that you’ll reuse over and over. Then setup auto-scaling and set thresholds based on the traffic you forecast.

When a threshold is passed, AWS will spinup a new instance of your webserver, and roll it into the load balancer pool automatically. Once traffic falls below the scale back threshold, Amazon will take a server out of the pool for you.

Be sure to monitor this activity to start with, and also run some load and stress tests on it. You want to ensure that it behaves as you expect, and no anomalous cases will cause you to spinup servers unnecessarily.

2. Horizontally Scale the Database Tier

MySQL offers a number of solutions here. You can configure MySQL in a master-master active passive cluster, also known as circular replication.

In this configuration, MySQL will send all completed transactions to the other server in the cluster. Your passive server can also handle read traffic for your application. At the same time as you achieve high availability, you also get scalability by sending much of the SELECT traffic off to another server.

As the load grows further, roll in an additional read-only slave into your setup.  You can then further scale out reads.  As you do this, you’ll continue to send all writes to the single active master database.

As an alternative, you may wish to employ Amazon’s RDS solution, which is based on the MySQL community server, but with certain locked-in settings. In this configuration, you will not be able to use an alternate MySQL distribution such as Percona’s high-speed server.

What this configuration does offer is multi-az configuration. Keep in mind though that any MySQL server you spinup will have a region and availability zone as part of its configuration, so you are always free to use those features of Amazon’s network to increase availability.

If the load on the single master database continues to be a problem, you can vertically scale that node in place. Do this by spinning up a new larger EC2 instance on an EBS root volume. Then detach that root volume, stop your old instance, detach its root volume, and move it over to the new server.

Once you attach that live root volume, your new larger EC2 instance will be your original server, scaled UP in place!

3. Use Striped EBS Volumes

EBS is a great technology, as it brings the flexibility of a storage area network to each of your EC2 instances.  It’s not without its challenges though, and at times you will experience great variability in disk I/O throughput.

This can pose a challenge for the database tier especially.  Keep in mind too, that Amazon’s infrastructure virtualization layer will dial up or dial down the amount of disk I/O your instance receives based on how large the instance is.

One additional way to get better EBS performance is by using Linux’s software raid technology.  Since EBS already has redundancy built in, you can simply use striping or RAID 0 across a number of EBS volumes – we recommend four.

Be careful with such configurations as each of your EBS volumes won’t operate by themselves now, but require all four to be complete.  This will impact EBS snapshot backups, as well.

Frequently Asked Questions (FAQs)

Why Is Cloud Scalable?

Cloud is scalable because of the visualization of Virtual Machines (VMs). The resource and performance of VMs aren’t relatively set as physical machines. They are highly flexible and can be scaled up and down easily.

What Are Cloud Scalability Options?

There are two basic options for scalability in cloud computing: vertical scaling and horizontal scaling. Vertical scaling is also known as “scaling up” or “scaling down”.

What Is an Example of Cloud Scalability?

When the number of visitors increases it slows down the cloud server; As a result, it may delay the website and affect customer service. Moving the website to a larger virtual machine (VM) can increase server performance. This is an example of cloud scalability.
