Cloud computing represents a huge advancement for small and large businesses alike. Organizations will evolve their data solutions from hardwired datacenters to an architecture where applications run on dynamic and dedicated servers in automated environments. Cloud computing environments offer large advances in computing resources at minimal costs to the subscribers. With cloud computing businesses will find modern-day convenient solutions at hands reach, and these solutions fit their needs anywhere and anytime.
At present cloud computing does not mitigate security risks. That's right, the same security risks that target enterprises and the web are still in play in cloud computing. A shared responsibility model helps customers and providers clearly define and understand what each identity has for security responsibilities. In most cases, the cloud provider secures the cloud and its physical data centers, as well as its foundational networks. The cloud customer also holds responsibility for security while working in the cloud; including responsibility for their operating system, software, applications and data they bring with them. Cloud computing relies on shared resources and requires best practices for positive results. Security best practices show that critical applications and data are best separated into secure segments, similar to the idea of a blockchain where each link of the chain is secured and holds different data.
In cloud environments Virtual Machines (VMs) communicate directly with other Virtual Machines within a host server, each Virtual Machine may have a different allocated trust level. Cloud computing environments are highly dynamic which results in security policies being stressed by changing scenarios as new cloud workload deployments are communicated between VMs. Infrastructure as code or (IaC) has become a go-to solution to secure configurations and misconfigurations inside the cloud while rapidly creating an immutable infrastructure. An immutable infrastructure has the unique ability to freeze many parts of cloud infrastructures as needed, making results more predictable when running codes. If you know every node in your network has the same virtual networking configurations it will be much easier to make changes or problem solve.
