If you want your business to keep up with the latest tech trends and make full use of the modern-day tools that it has at its disposal, then you need to migrate to the cloud. Once you make this leap into the unknown, you’ll probably wonder why you didn’t make it five years ago!
There are a host of benefits to be reaped from cloud migration, some of which include faster deployment times, enhanced security features, greater capacity for workforce collaboration and less infrastructure complexity than usual IT architecture. Should you decide that these rewards are too great to miss out on, you need undergo a cloud migration right away. When you do decide to make this transition, just be sure to remember the advice laid out below.
Here are two key components of successful cloud migration:
Take the shared responsibility of cloud security into account
Like all other technologies that are linked intrinsically to the web, the cloud does come with its fair share of security concerns. Cloud providers have come up with the concept of shared responsibility model for cloud security. This usually means that the cloud provider takes responsibility for certain aspects of the security, specifically around hardware and physical security, while the customer is responsible for other aspects, such as the applications built in the cloud, the data that’s stored in these applications, etc.
There are many things you can do to ensure you deliver on your end of the cloud security’s shared responsibility.
Ensuring data security
When it comes to securing data in the cloud, there are several ways to achieve that:
- Limit access to the data using role-based access control
- Encrypt data at rest
- Using third party tools such as data loss prevention software to prevent unauthorized access and retrieval of data
Ensuring application security
If you’re building your apps in the cloud using the latest technologies like Docker, Kubernetes, Istio, or the like, you must take additional steps to ensure your applications are resilient against hacking and breaches. These include:
- Shift-left with security, starting with scanning your container images before you deploy anything into production
- Protect your applications from misconfigurations and overly permissive network policies
- Ensure that your containers are protected during runtime by detected unwanted or unexpected processes
There are a lot of online resources for helping to ensure the security of your Kubernetes-managed applications that you should familiarize yourself with. Now that you have a working knowledge of the Kubernetes security issues that you are liable to face when you migrate to the cloud, you can take action with regards to deterring them and minimizing the impact they have on your business.
Choose your migrated applications carefully
Unfortunately, not all of the applications that you use on a daily basis are going to be able to survive your cloud migration, simply because some of them just won’t belong in that environment. It is for this reason why you must choose which apps you are going to migrate carefully, taking cost and security into consideration when you do. Some apps will be far too expensive to move and others will be easy to hack into when they are stored in the cloud, which is why you have to weigh up the pros and cons of each application and decide whether each of them are worth the effort of being migrated into the cloud.
As you evaluate which of your applications are going to be moving with you into the cloud, be sure to consider the following all-important questions:
- Can your applications be moved in their current form, or will they require a redesign?
- Will said redesign be too complex and ultimately not worth the hassle?
- What will the ROI be on each application that you choose to migrate?
