Meeting the Scalability Challenges of MSPs

Adding infrastructure or increasing the size of operations requires setup time. You may not have the time to scale quickly.

In some cases, MSPs face strict limitations on the size of their infrastructure. For example, if you rely on an on-premise server rack, you only have so many servers. Scaling beyond that number is difficult because of the setup time and acquisition cost of new servers.

Scaling requires not just changing the size of infrastructure, but also the size (and, sometimes, the nature) of management processes and teams. Those are challenging items to modify.

Predicting your future operations needs is difficult at best. You may gain or lose customers unexpectedly. Scaling seamlessly requires you to react instantly to these types of changes, which is hard to do.

Automate, automate, automate. There are many reasons to automate everything in your business, and scalability is a big one. If processes such as infrastructure provisioning and application deployment are automated, it is much easier to increase the volume of your operations quickly.

Rely on tools, not people. To the extent possible, your business should be built around tools, rather than people. Tools can quickly be reconfigured or upgraded when you need to scale. Changing the work that people do, and the number of people who do it, is harder. Obviously, people will always be an important part of your business, and tools can’t replace them everywhere. But consider using tools (such as Infrastructure-as-Code platforms, or automated monitoring software) in order to perform tasks that are currently assigned to human beings.

Develop scalability “playbooks.” A playbook is a plan that defines how you’ll react to given circumstances. They can be used to develop paths for handling everything from security incidents to infrastructure failures to, yes, scalability needs. If you invest time before scalability pressures arise in developing a plan for how you’ll increase or decrease capacity, you’ll be better able to scale quickly when the time comes.

Adopt modular architectures. Software, infrastructure and business processes that are modular—that is, composed of multiple discrete pieces—are easier to scale. That’s because, in some cases, scaling requires you to modify one part of the system, but not other parts. If you have a monolithic system where all the parts of deeply entwined, scaling can be much more difficult.

Move to the cloud. By now, you’ve no doubt heard hundreds of reasons why you should move to the cloud. But if you still need convincing, think about scalability. In the cloud, you can increase or decrease resource consumption on demand. Plus—and this is the more novel argument in favor of cloud computing—modern cloud platforms provide innovative services, such as serverless computing, that offer new scalability opportunities.
