Cloud Strategy/Cloud Migration
CIO Magazine indicates that the biggest challenge for most companies (77%) is finding and deploying a service that is the right fit.
Gartner forecasts Cloud Computing to be a $300 billion business by 2021, as companies increasingly adopt Cloud services to realize their desired digital business outcomes. Through the use of Cloud services, Cloud Computing provides the speed and agility that digital business requires.

History of Cloud:
To understand Cloud we have to understand the concept of Virtualization.
Virtualization is at the heart of Cloud Computing. You can have Virtualization without Cloud but not the other way around.
Simply explained, Virtualization is the use of software to simulate the existence of hardware. Each simulated server is called a Virtual Machine (VM), and even though it is virtual, it has the appearance of a self-contained computing system with its own operating system, processors, memory, drives, etc.
Server Virtualization isolates the various Virtual Machines (VM) and allocates / controls the resources that can be utilized by each VM.
A company that in the past needed many servers to run different business applications can now use a reduced number of servers, saving space, equipment cost, network management charges, etc. Virtualization allows you to get more out of your hardware and maximize your budget.
Virtualization gives resource centralization, optimal resource utilization and some redundancy against individual server failures. This also takes care of re-provisioning resources during seasonal bursts in traffic.
Cloud Computing took Virtualization to the next level. Virtualization is about technology. Cloud is about features, service and a deployment model.
The National Institute of Standards and Technology (NIST) defines cloud computing as “a model for enabling on-demand network access to a shared pool of resources that can be rapidly provisioned with minimal effort or interaction.” The five essential characteristics of cloud computing are on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service.
Cloud Services (SaaS, IaaS, PaaS). The cloud is a very broad concept, and can refer to different kinds of online service, but for businesses there are three cloud service types to consider, Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Different types of cloud services provide different levels of readiness or development.
Infrastructure as a Service (IaaS) is the type of Cloud Computing service that provides the “raw materials” for IT. The User usually pay for the resources they consume including CPU cores, RAM, hard disk or storage space and data transfer. IaaS is the least ready-made cloud computing service, which means it offers developers the most control because it’s as close to hardware as you can get. Microsoft Azure, Google Cloud and Amazon Web Services are the dominant IaaS vendors.
Platform as a Service (PaaS) provides the next level of readiness or development. It is a service delivered mostly to developers and architects.
The main idea of PaaS is that it hides the infrastructure from users and provides additional functionality on top of the infrastructure. For developers and architects, this means spending more time using platform functionality to drive business value rather than sorting through complicated infrastructure concerns.
One of the most popular PaaS use cases is database as a service — for example, AWS Relational Database Service (RDS).
Software as a Service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers to use remotely over the Internet. Example of SaaS are CRM applications like Salesforce and office productivity applications such as Office365 online.
Cloud Environments: Cloud environments are the different conditions and settings in which the Cloud services operate. Private, Public or the combination of both (Hybrid).
Cloud provides self-service capability, elasticity, automated management, scalability and pay-as-you-go service that is not inherent in virtualization.
Private Cloud. In a Private Cloud environment the client owns or leases the hardware and software that provides the consumption model. You pay for resources as you go, as you consume them from a vendor who is providing such resources to multiple clients, often in a co-tenant scenario. Self-service and on-demand resource allocation are key features of the private cloud which aren’t inherent to all virtual environments.
Public Cloud. While private clouds are operated by internal teams, the public cloud is a service offered to external parties in an environment open to many users, built to serve multi-tenanted requirements. There are many considerations when adopting the Public Cloud such as privacy, security, performance, cost, flexibility, control and compliance, but the potential benefits are sufficient to entice even the most demanding organizations.
Hybrid Cloud. A true hybrid cloud is when public and private cloud environments are woven together into a single seamless experience.
Cloud solutions are best for companies that:
- Want to outsource systems’ support and free up their IT staff so they can concentrate on more strategic projects. (From Caretaker to Decision Maker)
- Are constantly changing and require quick setups.
- Work better with an OPEX (Operational Expenditures) model.
- Require fast scale (up or down), flexibility and don’t have too many security concerns.
