Migrating to the cloud is no small task, it’s a colossal change. Therefore, understanding the nitty gritties of cloud computing while addressing the challenges is the whole ball of wax. Although cloud computing continues to gain acceptance, the misconceptions remain intact. Along with the bewildering range of promises that cloud computing brings for the global IT sphere, comes confusion.
So let’s deep dive into these frequently asked questions about cloud computing and get a better insight of what it is all about.
- What is cloud computing? The Urgent Business Imperative
Cloud is about the way you do computing, not where you do computing. Worldwide Cloud spending is predicted to touch $565B by 2021. Is your organization still storing data and software on hard drives and servers?
Introducing Cloud computing, a delivery-model that involves the delivery of resources such as network, storage, applications, or software from a centralized location. The procedure involves using a network of remote servers, hosted via the internet to provide highly scalable, on-demand access to computer resources. In a nutshell, clouds are marked by self-service interfaces that let users acquire resources at any time and get rid of them when they are no longer needed.
- What are the different types of cloud computing?
The types of cloud can be divided into the following four categories:
- Private Cloud
In this model, the deploying entity sets up an exclusive on-premise data center that delivers resources like network, compute, and storage. In several cases, a private cloud may also involve colocation to curtain the exorbitant hardware cases.
- Public Cloud
In the public cloud, a third-party cloud service provider provides the above resources to a large number of enterprises. Hence, this cloud model is based on the principle of pooled or shared resources. In the public cloud, resources are provided to customers through metered services, and a cloud vendor is responsible for back-end maintenance.
- Hybrid Cloud
A hybrid cloud is a combination of third-party and on-premise data centers. A hybrid cloud strategy can be an excellent choice for organizations to avail greater flexibility by moving workloads between clouds as costs and needs fluctuate.
The multi-cloud is an integration of multiple public cloud providers or a combination of both public and private clouds. The possibilities are limitless in multi-cloud, but the cloud model is challenging to manage and integrate.
- What are the perks of Cloud Computing? The Powerhouse to run your Business
Cloud computing can significantly lower down IT costs as the CSP manages the underlying infrastructure. Apart from the reduced IT costs, companies can seize the benefit of scalability and flexibility of work practices. Cloud ecosystems are compatible with multiple operating systems and devices, and they are generally more secure as compared to the on-premise ones. Data is money, and in the cloud infrastructure, enterprise data is centralized, making it easy to maintain and secure backups. The cloud is global, immensely scalable, convenient, and easily accessible. All these features empower organizations to reduce the time required for deploying software applications.
- How to find out whether a Cloud is right for my business?
To find out whether a cloud infrastructure is right for any working framework or not, enterprises should evaluate their current IT setup. In addition, company leaders should also evaluate the costs of the cloud and consider the ease of migration along with their in-house technology landscape.
- Is the Cloud Secure? Tight, but not infallible.
Safety misconceptions and the fear of security breach go hand-in-hand with cloud migration. However, clouds themselves are generally more secure than most private data centers. CSPs offer architectural options to encrypt data, isolate workloads, and detect potential threats, making the cloud secure than any on-premise environment.
- How to prepare for the Cloud? Gear up for the Cloud World.
The first step in preparing for the migration is developing a clear strategy with quantifiable goals. Industries need to identify leaders to evangelize the use of the cloud. Enterprises need to ascertain the requisite capability of their IT professionals to manage and undertake the new cloud service.
- How to develop a Successful Cloud Strategy?
For developing a clear and concise cloud strategy, organizations need to answer a basic question: “Will they be moving their existing workloads over to the cloud or adopting a sustainable infrastructure afresh.” Enterprises need to generate a holistic strategy after considering the security and compliance issues and thinking about how the cloud aligns to their strategic objectives.
- Which Workloads can Organizations move to the Cloud?
By 2021, 94% of workloads will be processed by cloud data centers.
In theory, any workload can be moved over the cloud infrastructure. However, enterprises need to consider the impact of the migration to meet all regulatory compliances where applicable. Large, monolithic applications with relatively predictable and constant loads are more cost-effective on-premises. Moving an application as-it-is to the cloud is typically not the best option. An application can be broken down into microservices to benefit from the service-based approach of IaaS.
- How is Cloud Computing different from Grid Computing? Centralized vs Collaborative Pattern
In the case of cloud computing resources are centrally managed, whereas grid computing follows a distributed computing architecture. Cloud computing uses services like PaaS, IaaS, and SaaS, and it is accessible through standard web protocols. Grid computing uses systems like distributed pervasive, distributed computing, and distributed information, and it is accessible through grid middleware. But, in the cloud, scalability is high, the costs are low, and enterprises can get the benefit of increased productivity, efficiency, and disaster recovery.
- How much does the Cloud cost? Public Cloud? Private Cloud?
Evaluating the exact price of cloud services can be slightly complex. The costs vary wildly depending on multiple variables, including the provider, the size of your environment, the amount of data movement, etc. Public clouds charge per user-basis, and there are pricing schemes that can lower costs. Organizations often hesitate to move to the cloud because on-premise computing is believed to be more affordable. But the cloud is the future and if modernizing an IT department is the goal, then the cloud is the only route that needs to be taken.
Don’t be a Laggard. Business Continuity has been made possible with Cloud Computing. Let Experts handle your transition to the Cloud.
Confusion is natural while operating the cloud, and so working with experts can make the work easier and swifter. Organizations need to hire experts or train their in-house team to make the migration to the cloud smoother. Depending on the layer of the cloud stack, companies need to train their IT staff to acclimatize them with the process. Some areas need special integration, configuration, and a keen understanding of the shared responsibility model. Cloud computing is a continually evolving domain. Therefore, a well-planned transition should be coupled with selecting the right Cloud Service Provider to attain the desired results.
