The public cloud is a hot topic in IT today. Even though it has been around for about ten years, cloud offerings from AWS, Azure and Google cloud have made the public cloud more mainstream and easier to get onto. In some instances though companies are jumping on board without really understanding it. So in an effort to debunk some myths here are five myths to consider if you are contemplating moving to the public cloud:
1. Public Cloud is Cheaper
The AWS/Azure public cloud “pay by use” methodology was a huge game changer for companies jumping onto the pubic cloud, but there is an assumption that “pay by use” will automatically make the subscription cheaper.
It can in some instances, but it should be noted that in many cases High Availability environments will usually come out cheaper with a hosting provider rather than a public cloud option. Data out transfer costs and dedicated resource costs both come into play in a big way in a High Availability environment, and things can get very expensive, very quickly. Many companies have tried out the public cloud and have gone back to dedicated resources in a managed cloud where the investment is more reasonable and consistent.
2. Everything should go to the Public Cloud
Due to the time it can take to tailor your application to the public cloud (not all applications are really built for the cloud/virtualization, much less the public cloud), not all companies environments are sitting in the public cloud. You really need to have an in-depth discussion with your IT Provider to determine what can be in the public cloud and what should be in the public cloud.
3. Full Security/Compliance Comes with Cloud Infrastructure
Security is much better in the cloud today than it has been in years past. Even though public cloud offerings like AWS and Azure offer HIPPA or PCI compliant solutions, it does not mean that will automatically make you compliant on moving to the public cloud. The infrastructure they provide to you is compliant, but once you configure your application on top of it, it becomes a completely different story.
4. Moving to Public Cloud is Simple
Some applications can be moved to the cloud simply, however putting a full environment that has not been configured and is technical within itself is a different story. Use your IT Provider or someone with the right expertise and experience to migrate the environment as it can get complicated quickly and without a good foundation getting your application to work on top of it may end up being expensive.
5. Managing the Public Cloud is Simple
Once someone has designed, built and migrated your application to the public cloud, it should be simple to manage from there – surely? You would think so but it is not the case! You really need to have your IT Provider work on maintaining, tweaking and scaling the configurations to keep your cloud “humming” along.
The simple suggestion here is to let the experts build, migrate and manage it for you. Cutting corners in the public cloud will come back to bite you.
