Cloud Computing is defined as manipulating, configuring, and accessing applications online. So It offers online data storage, infrastructure, and application.

Cloud computing basics tutorial for beginners

There are several types of services and models working behind the scene making cloud computing feasible.

  • Accessible to end users. Following are the working models for cloud computing:
  • Deployment Models
  • Service Models – A. Infrastructure as a Service (IaaS) B. Platform as a Service (PaaS) C. Software as a Service (SaaS)
  • Then Cloud Computing has a lot of advantages. Most of them are mentioned below:
  • One can access applications as utilities, over the Internet.
  • Manipulate and configure the application online at any time.
  • It does not require to install a specific piece of software to access or manipulate cloud applications.
  • So Cloud Computing offers online development and deployment tools, programming runtime environment
  • Through Platform as a Service model.
  • Moreover Cloud resources are available over the network in a manner that provides platform independent access to any
  • Type of clients.
  • Cloud Computing offers on-demand self-service. The resources can be used without interaction with cloud
  • Service provider.
  • Cloud Computing is highly cost effective because it operates at higher efficiencies with greater utilization.
  • It just requires an Internet connection.
  • Finally Cloud Computing offers load balancing that makes it more reliable.

Most Common Security Threats for Cloud Services

Cloud computing continues to transform the way organizations use, store, and share data, applications, and workloads.

It has also introduced a host of new security threats and challenges. As more data and applications are moving to the cloud, the security threat also increases.

With so much data residing in the cloud public cloud. These services have become natural targets for cyber security attacks.

The main responsibility for protecting corporate data in the public cloud lies not with the service provider but with the cloud customer. 

Enterprise customers are now learning about the risks. Then spending money to secure their data and applications.

Steps in Cloud Adoption at Large Enterprises

Large enterprises have bigger challenges when it comes to migrating applications to the cloud. Migration to the cloud is often an evolutionary process in most large enterprises and is often a 4 step process. But not necessarily a sequential process, and can happen in sequence or in parallel.

Moving to the cloud requires complete buy-in from all business & IT teams. Moreover need a developer, compliance experts, procurement, and security.

Firstly step is all about becoming aware of cloud technologies and their implications. Then IT team will need to understand:

1. What are the benefits – Agility, cost savings, scalability, etc.

2. What is the roadmap for moving to the cloud?

3. What skills each team member will need?

4. Then How do legacy applications work in the future?

5. Hence Who are the partners in this journey?

Secondly, the step is all about experimentation and learning from those small experiments. These are typically PoC projects which demonstrate the capability & benefits. The PoC projects are needed to get key stakeholder buy-in.

The third step is essentially a migration of existing apps to the cloud. For example, moving emails to the cloud or moving office apps to  Office 365 cloud, etc. These projects are becoming a norm for large enterprises. Which have a rich legacy.

Fourthly step demonstrates the final maturity of the cloud. In this stage, companies now deploy all new apps on the cloud. You can see more definitions of what is Cloud Computing?
