A Beginners Guide to Cloud Computing!

Cloud computing refers to the delivery of computing services, including servers, storage, databases, networking, software, analytics, and more, over the Internet. Instead of storing and accessing data and programs on a personal computer or local server, cloud computing enables users to access these resources remotely, on-demand, and on a pay-per-use basis.

Cloud computing providers maintain and manage large data centres with powerful computing resources that are shared among multiple users and organizations. This allows businesses and individuals to easily scale their computing resources up or down depending on their needs, without having to invest in and maintain their own infrastructure.

Types of Cloud Computing:

Not all clouds are the same and not one type of cloud computing is right for everyone. Several different models, types, and services have evolved to help offer the right solution for the ever-evolving needs of the users.

First, one has to determine the type of cloud deployment, or cloud computing architecture, that their cloud services will be implemented on. There are three different ways to deploy cloud services: on a public cloud, private cloud, or hybrid cloud.

  1. Public Cloud: A public cloud is a cloud infrastructure that is owned and operated by a third-party cloud service provider, and is available to the general public over the internet. Public clouds offer high scalability, reliability, and cost-effectiveness. Examples of public cloud providers include AWS, Microsoft Azure, and Google Cloud Platform.
  2. Private Cloud: A private cloud is a cloud infrastructure that is dedicated to a single organization and is typically operated in-house or by a third-party service provider. Private clouds offer greater security and control over data but can be more expensive to set up and maintain.
  3. Hybrid Cloud: A hybrid cloud is a combination of public and private clouds, allowing organizations to leverage the benefits of both. With a hybrid cloud, an organization can store sensitive data on a private cloud and use the public cloud for less sensitive data or for bursts of high demand. Hybrid clouds can also help organizations avoid vendor lock-in and allow for greater flexibility in workload management.

Each type of cloud computing has its own advantages and disadvantages, and choosing the right type depends on an organization’s specific needs, budget, and resources.

The Three Main Types of Cloud Services:

Most cloud computing services fall into three broad categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). These are sometimes called the cloud computing “stack” because they build on top of one another. Knowing what they are and how they’re different makes it easier to accomplish your business goals.

  1. Infrastructure as a Service (IaaS): IaaS provides access to computing resources such as virtual machines, storage, and networking infrastructure. This allows businesses to build and manage their own IT infrastructure in the cloud, without having to invest in and maintain physical hardware.
  2. Platform as a Service (PaaS): PaaS provides a platform for developers to build and deploy applications without having to manage the underlying infrastructure. This can include tools and services for application development, testing, deployment, and scaling.
  3. Software as a Service (SaaS): SaaS provides access to software applications that run in the cloud, typically through a web browser or mobile app. This eliminates the need for users to install and maintain software on their own devices, and allows businesses to offer software applications as a subscription-based service.

Each type of cloud service offers different benefits and use cases. IaaS is often used by businesses that need flexible and scalable infrastructure resources, such as startups and small businesses. PaaS is often used by software developers who need to build and deploy applications quickly and efficiently. SaaS is often used by businesses that need access to software applications but don’t want to invest in and maintain their own software infrastructure.

Benefits of Cloud Computing:

Cloud computing is a big shift from the traditional way businesses think about IT resources. Here are six common reasons organizations are turning to cloud computing services:

  1. Scalability: Cloud computing allows organizations to easily scale their computing resources up or down as needed, without having to invest in and maintain their own infrastructure. This can be especially useful for businesses with fluctuating demands or growing workloads.
  2. Cost savings: Cloud computing eliminates the need for businesses to invest in and maintain their own IT infrastructure, which can be expensive. Instead, businesses can pay for only the resources they need on a pay-per-use basis.
  3. Flexibility: Cloud computing allows users to access data and applications from anywhere with an internet connection, enabling remote work and collaboration. It also allows businesses to easily add new users, applications, and services.
  4. Security: Cloud computing providers typically invest heavily in security measures to protect their customers’ data. This can include physical security measures, such as data centres with restricted access, as well as encryption and other data security measures.
  5. Disaster recovery: Cloud computing providers often have disaster recovery measures in place, such as backup and replication, to ensure that data is protected in case of a natural disaster or other catastrophic events.
  6. Continuous updates: Cloud computing providers typically offer continuous updates and upgrades to their services, ensuring that customers have access to the latest technology and features.

Overall, cloud computing offers many benefits that can help businesses and individuals save time, money, and resources while also increasing performance, productivity and reliability.

Uses of Cloud Computing:

You’re probably using cloud computing right now, even if you don’t realize it. If you use an online service to send emails, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes.

Due to the versatility and scalability nature of cloud computing, already a variety of organizations—from tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons.

Here are a few examples of what’s possible today with cloud services from a cloud provider:

  1. Create cloud-native applications: Quickly build, deploy, and scale applications– web, mobile, and API. Take advantage of cloud-native technologies and approaches, such as containers, microservices architecture, API-driven communication, and DevOps.
  2. Test and build applications: Reduce application development cost and time by using cloud infrastructures that can easily be scaled up or down.
  3. Store, back up, and recover data: Protect your data more cost-efficiently– and at a massive scale– by transferring your data over the Internet to an offsite cloud storage system that’s accessible from any location and any device.
  4. Analyze data: Unify your data across teams, divisions, and locations in the cloud. Then use cloud services, such as machine learning and artificial intelligence, to uncover insights for more informed decisions.
  5. Stream audio and video: Connect with your audience anywhere, anytime, on any device with high-definition video and audio with global distribution.
  6. Embed intelligence: Use intelligent models to help engage customers and provide valuable insights from the data captured.

These are just a few of the many ways that cloud computing can be used.

The ever-increasing popularity and demand of cloud computing due to its flexibility, cost-effectiveness and ease of use make it a valuable tool for businesses of all sizes and industries.
