Cloud is a huge step forward for IT infrastructure and application delivery, but on-premises still plays an important role for many business requirements
It seems not a day goes by when we don’t hear the word “cloud” when talking about business technology. Does that mean private server and storage equipment will eventually be a thing of the past? There are still numerous use cases where on-premises suits business needs better than a cloud service and at Tecala we’re all about choice for our clients so let’s take a look at why on-premises still matters.
USE CASES FOR ON-PREMISES
With the cloud juggernaut in full swing and new services appearing daily, there are still use cases for on-prem the cloud doesn’t yet satisfy. Here are a few to consider:
Remote locations: Unfortunately in Australia we still suffer the tyranny of distance where fast, business-grade networking services are not available. It might be possible to use cloud services in remote locations, but in many cases it’s just not practical to wait hours for data to be sent to and from a cloud.
Application support: Many enterprises applications are not yet available as a cloud service and on-prem still provides a way to control – for better or worse – the upgrade cycles of such applications.
Regulatory compliance: Some organisations aren’t permitted to store their data outside the country (or in some cases jurisdictions). On-prem wins here, albeit by force.
WORKLOADS GO ONTO (AND COME OFF) THE CLOUD
With all the hype about cloud, it’s tempting to think it is a one way street away from on-premises IT. This is not always the case and many workloads do come off the cloud for various reasons:
Performance: The “best effort” performance of cloud services sometimes isn’t enough for highly demanding workloads.
Capacity: The cloud is good for scalability, but costs can easily get out of control. For example, earlier this year Dropbox announced it moved off the cloud to its own storage infrastructure.
Flexibility: At the end of the day if you have control over the infrastructure you have the most flexibility with how it’s used. This might be another “for better or worse” scenario, but clouds are designed to serve millions, not individual organisations.
A final point worth considering is risk management. Does your organisation have a business continuity plan if a cloud service were to go offline? Is your data backed up off the cloud?
All questions on-premises still provides an answer to.
