What is Cloud Computing

Cloud computing is the delivery of different services through the Internet on a pay-as-you-go basis. These resources include tools and applications like data storage, servers, databases, networking, and software.

Rather than saving files on a proprietary hard drive or local storage device, cloud-based storage makes it possible to save them to a remote database with access to internet.

Cloud computing is a popular option for people and businesses for a number of reasons including cost savings, increased productivity, speed and efficiency, performance, and security.

Some major examples of cloud computing you’re probably using are :

  • Google drive
  • Apple iCloud
  • Drop box
  • Slack

The major cloud computing providers are

  • Microsoft Azure,
  • Amazon Web Services  
  • Google Cloud
  • Oracle Cloud
  • IBM Cloud
  • Salesforce

Why Invest in Cloud Computing?

The Covid-19 pandemic has made more companies dependent on cloud-based services to drive that change. Increasing the demand, the work-from-home trend is expected to remain that might evolve into a hybrid model in the post-pandemic period.

Cloud will power the way companies adapt to the “new, unstable normal”. Cloud Services providers will experience continuous growth that will revolutionize how we store and get data.

In a study by Markets and Markets Research Private Limited, in 2020, the global cloud computing industry was estimated at $371.4 billion. By 2025, the value will grow to $832.1 billion with a Compound Annual Growth Rate (CAGR) of 17.5%.

Cloud computing has the ability to give customers high-quality, quick-loading networks and applications which will improve network and storage quality. This high standard of quality would also contribute to increased business quality over time.

Types of Cloud Computing

  1. Public Cloud – This type of cloud is available to the public and is provided by a third party.

2. Private Cloud – Private Cloud is owned and operated by one organization. An organization like a corporation or college can create it’s own infrastructure for a private cloud either onsite or at a remote location. Private clouds are not accessible to the public. These can also be called a corporate cloud, internal cloud, or on-premises cloud.

3. Hybrid Cloud – Hybrid Cloud uses both private and public cloud for it’s computing needs. In this case, an organization will use it’s private cloud for critical functions while using a public cloud when it’s computing needs are in higher demand.

Types of Cloud Services

  1. Software -as-Service (SaaS) – SaaS allows users to connect to and use cloud-based apps over the internet.

Example of SaaS applications are Sales force, Skype, Office 365 and Dynamics Customer Relationship Management (CRM) Online

2. Infrastructure-as-a-Service (IaaS)

IaaS is simply a hosting model that controls management of business models.

Example of IaaS applications are Virtual Machine, VNET.

3. Platform-as-a-Service (PaaS)

PaaS is a complete development and deployment environment in the cloud.

 Example of PaaS applications are Storage, Search, SQL and App Service.

Benefits of Cloud Computing

  1. Business Agility- i.e. ability to adapt to change to market, environmental and cost effective ways.
  2. Scalability
  3. Elasticity
  4. Fault Tolerance
  5. Disaster recovery
  6. High Availability
  7. Cost Effective
  8. Access to automatic updates

In conclusion, Cloud Computing is cost effective for many companies and allows them focus on competence instead of on matters of IT and infrastructure. An emerging related cloud technology and services relates to artificial intelligence (AI) and machine learning. These technologies provide a range of cloud-based, ready-to-use AI and machine learning services for client needs. Google Cloud Machine Learning Engine and Google Cloud Speech API are examples of these services. Microsoft Azure Machine Learning Studio, Amazon Machine Learning, Amazon Polly, Amazon Lex.
