Cloud computing permits developers to create, configure, and personalize apps over the internet. Cloud technology includes a programming platform, hard drive, software program, and database.
In this post, we will discuss cloud computing, how it can transform the way you operate, and why you should select cloud computing. What are the advantages and disadvantages of cloud computing? Also, what are the models that it works with?
Before jumping to its countless benefits, let me give you a brief note on cloud computing.
Cloud computing is the on-demand availability (the term refers to as you can use it anytime whenever you need to store data ) of computer system resources, where you can store data on the internet, and your data is managed and operated by the service providers who especially deal with cloud computing.
Cloud computing is continuously booming across the various industries as the growing innovation and development require plenty of resources in a well-organized manner, operating and managing all itself is not handy, therefore we require other resources upon which we can rely.
Also, when we think of distributing our work with another service provider or organization then trust is our major concern. This is the main reason why cloud computing is all we need to scale up our business without any trust concern and it easily operates and manages all of our work with a world-class privacy system.
Cloud computing provides you the different services through the internet like data storage, servers, database, networks and etc.
According to IDC, global cloud computing spending has hit $706 billion and is expected to reach $1.3 trillion by 2025.
As the business grows we need more space to save our data for backup, at the same time managing all the data efficiently is not possible manually. On the cloud, you can easily upload and save your data and retrieve them on demand.
Most importantly, it enables you to work remotely, so you don’t need to be in a specific place to gain access to your data or files. There is an ample number of providers that provide cloud services to the users and it is completely safe to use the service. It has immense benefits.
What are the characteristics & drawbacks of cloud computing?
- Agility – It enhances your flexibility by adding, re-provisioning, and upgrading digital infrastructure
- Cost reduction – On-premises system requires an additional team to maintain and monitor which may increase your overall cost on the other hand if you choose to cloud service then it can really reduce your cost of maintenance. As it converts your capital expenditure into operational expenditure, you will need to pay for what you have used, not more than that.
- Device and location independence – It allows you to access systems via a web browser from any location and using any device
- Maintainance – Maintaining data and all other stuff that you want is all done by the service providers and it is really easy for them to handle them, by doing this you don’t need to invest in any data center hardware.
- Multitenancy – it allows for the distribution of costs and services among a large group of users
- Performance – A team of IT experts is always available to monitor the performance.
- Productivity – Productivity may increase as several users will work on the same data at the same time, rather than waiting for it to be saved and emailed.
- Availability – The integration of many alternative sites boosts availability, making well-designed cloud computing ideal for business continuity and emergency recovery.
- Scalability – If compared to on-premises, cloud computing lets you pay for how much you use with much faster and simpler provision for scaling up and down. When you scale up, it is tough to scale down, which often leads to huge losses in terms of infrastructure and expense.
- Security – As compared to conventional IT security, data security is a lot better, letting you skip regular monitoring and management of security calls.
- Public Cloud – It is another application development model, where a third-party provider manages your data. The service provided may be free or need a paid subscription.
- Private Cloud – It is managed and hosted entirely for a single business, whether internally or by a third party.
- Hybrid Cloud – A fusion of a public cloud and a private environment that are independent units but are linked to bring the benefits of diverse deployment types.
Cloud Computing Service Model
IAAS – It is the cloud computing platform layer that removes the requirement for an entity to maintain its IT infrastructure. It can be used to outsource IT architectures involving servers, networking, computing, storage, virtual machines, and so forth. but you only have a pay-per-use mechanism to access these resources via the Internet.
PAAS – It is a platform as a service that allows developers or programmers to quickly create, test, execute, and publish web applications. It includes infrastructure servers, “storage,’ and ‘networking,’ as well as platform middleware,’ ‘development tools,’ ‘database management systems,’ and other components.
SAAS – A software distribution model which is also known as ‘on-demand software, where services are maintained by the service providers. These services are available on the internet, so you don’t need to install any type of software to do that.
