Solutions

There are multiple reasons for widespread cloud migration, but they all share a common theme: For most businesses, the cloud simply works better than so-called on-premises, but that might not always have to be the case.
 

And it isn’t just about money. While any organization is interested in cutting costs, it is not the only thing they make the decisions to move their business to the cloud, which may ease of management, and archival.

 

Some reasons behind the decision making

 

  • The cloud has matured. It is no longer an untried, untested, risky product. Organizations don’t have to feel like they’re guinea pigs, being used to help work the kinks out of a new technology.

  • The big players are on board—from Amazon to Cisco to Microsoft—with mature cloud computing and data center technologies.

  • Yes, money is a factor, in several ways.

    • ROI is easier to forecast, and implementation costs are minimal.

    • Storage is easier and less expensive.

    • It is scalable without breaking the budget, enabling both online and geographic expansion.

    • It lets an organization do more with less downtime, cost, and loss.

    • It reduces infrastructure overhead.

  • The cloud is reliable. There would be no vendors in the market if it isn’t.

  • It is highly available.

  • It gives remote employees access and the ability to work over the internet.

  • It offers better security. While there is some debate among experts about this, many say the cloud overall can provide better security than its customers have on-premises. Some providers will track and update underlying server and other software, and do database backup and periodic maintenance.

 

Cloud native applications. It refers to applications developed and built specifically for the cloud. Companies providing these services are mainly called Cloud Service Provider (CSP). Obviously, these apps are designed to integrate well with the cloud computing architecture and to take advantage of a CSP’s computing frameworks and services.

 

Cloud easiness brings also the risk

All this comes with a caveat, however. Organizations shouldn’t think they can simply migrate workloads, storage, applications, and other operations into the hands of a CSP and forget about security because “they’ll take care of it.”

 

While your specific environment will determine the risks that apply to you, there are some general drawbacks associated with cloud migrations that you will want to consider.

  • If your application stores and retrieves very sensitive data, you might not be able to maintain it in the cloud. Similarly, compliance requirements could also limit your choices.
  • If your existing setup is meeting your needs, doesn’t demand much maintenance, scaling, and availability, and your customers are all happy, why mess with it?

  • If some of the technology you currently rely on is proprietary, you may not be legally able to deploy it to the cloud.

  • Some operations might suffer from added latency when using cloud applications over the internet.

  • If your hardware is controlled by someone else, you might lose some transparency and control when debugging performance issues.

  • Noisy “neighbors” can occasionally make themselves “heard” through shared resources.

  • Your particular application design and architecture might not completely follow distributed cloud architectures, and therefore may require some amount of modification before moving them to the cloud.

  • Cloud platform or vendor lock-in: Once in, it might be difficult to leave or move between platforms.

  • Downtime. It happens to everyone, but you might not want to feel like your availability is controlled by someone else.
