Now we all know that the cloud is here to stay and it is important to familiarize yourself with it. As well as users, by reading up on the subject and experimenting! With 81% of organizations having at least one application or part of their architecture in the cloud. And high chances are there that your company has already invested in the cloud. But how familiar are you with the different type of cloud like hybrid clouds, multi cloud and are you using the right mixture of solutions for your company’s needs?
Private, public, and hybrid clouds are different ways of deploying applications in a cloud computing model. So, A public cloud is an environment made available over the internet, that anyone can subscribe to and can access to it. However, A private cloud, as the name implies, is the infrastructure used by just one organization. So, A hybrid clouds is a combination of the two other types.
All three cloud architecture provide a common set of benefits over traditional on-premises IT environments. And that is affordability, reliability, scalability on demand, and consistently high performance. The infrastructure choice depends on a number of factors including the kind of workload, security needs, budgetary considerations, and the extent of your in-house IT expertise. In fact, companies that are deploying cloud infrastructure is increasing. In this blog, We will discuss three main architecture in the cloud: Public, Private and hybrid clouds. We will explore difference between this three cloud so that you can choose best for your organization.
Public clouds are the most extensive and well-known cloud computing architecture. All the resources needed to run the organization. However, Servers, storage, networking components, and supporting software – are owned and managed by the third-party service provider. And accessed by your users over the Internet via a web browser. For Example of public clouds are Amazon Web Services, Microsoft Azure, and Google Cloud Platform. However, These providers offer Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) features on a pay as you go business model. So, Making it cheaper and easier for their user to access cloud based architecture on an as-needed basis.
Advantages of Public Cloud:
➠ Lower cost
➟ Pay-per-Use Pricing
➠ Freedom from maintenance
➟ Tax Benefits with OpEx vs CapEx
➠ On-demand scalability and High reliability
➟ Less complexity
➠ Rapidly Scale Computing Resources
Challenges of Public Cloud:
➠ Data Gravity Concerns & Vendor Lock-In
➟ Loss of Control over IT Infrastructure
➠ Limited infrastructure visibility and control
➟ A poor fit for sensitive and confidential workloads
➠ Security Concerns in Multi-Tenant Environments
Private cloud architecture is also known as “corporate cloud” or “internal cloud”. Instead, This cloud computing environments accessed by a single organization or customer. However, It can be located at your own data center facility or at that of a third-party service provider. So, The main characteristic is that the IT resources are run and maintained on a private network for your self use. However, A company may deploy a private cloud architecture from its on-premise data center or from rented infrastructure in an off-site data center. So, Some companies contract with MSPs(managed service providers) who host and manage the customer’s private cloud deployment in the MSP’s service center.
Advantages of Private Cloud:
➠ Tight security and High performance
➟ Keep Control of IT Infrastructure
➠ Protect User Sensitive Data
➟ Regulatory compliance and Scalability
➠ Meet Legal Compliance Requirements
➟ Flexibility to respond to need of change
Challenges of Private Cloud:
➠ High CAPEX and overhead
➟ High Ownership Prices
➠ Limited user access
➟ Integrating New Technologies
➠ Scalability Problems
A hybrid cloud architecture is a computing infrastructure that includes a public IaaS platform and a private or corporate cloud deployment, and the technology to connect these environments and orchestrate workloads between them. A hybrid cloud enables the company to meet it’s technical and business aims more cost-efficiently and effectively than it could with either a public or private cloud alone. So, Application interoperability, workload portability, and data portability are all necessary for an efficient and effective hybrid cloud infrastructure.
Advantages of Hybrid Cloud:
➟ Balance with Security and Scalability
➠ High flexibility and Optimized resource
➟ Manage Disaster Recovery
➠ Ease and agility
➟ Cloud Bursting to Meet High level Service Demand
Challenges of Hybrid Cloud:
➠ Complex Implementation
➟ Elevated cost
➠ Application and Data Portability Problems
➟ Managing Resources and IT Spending
How to Choose Cloud Model?
There’s no perfect solution when it comes to make a chice between the most efficient type of cloud deployment for your company. However, Your decision rely on numerous factors, including your desired use cases for cloud services. And so your company’s budgetary and technical limitations. It is must to keep in mind when deciding whether to choose a private or public cloud, to properly weigh the differences against each other. So, In most cases user see it as advantages or disadvantages, depending on the usage required. However, If we had like to store our backup data somewhere in the cloud, it’s important to know the sensitivity of said data.
A hybrid clouds model is most appropriate for:
➟ Organizations serving multiple vertical markets with different IT security, regulatory, and various performance requirements
➠ Optimizing the overall cloud investment while leveraging the benefits of both public and private cloud models
➟ Providing high level security for solutions such as SaaS workloads that need to be delivered via secure private networks
➠ An agile cloud architecture dictating frequent alternation among providers and clouds to obtain the best combination of price and performance for various workloads
A public clouds model is most appropriate for:
➠ Computing needs prediction, such as communications services for a mostly fixed number of users
➟ Software development and test environments
➠ Reserve resources provisioned to meet high usage situations on demand
➟ Applications and services needed for IT and business operations
A private clouds model is most appropriate for:
➠ Highly-managed industries and government agencies
➟ Technology companies that require strong control and high security over their IT workloads and underlying architecture
➠ Companies with the resources and requirements to invest in advanced technologies delivering the best performance and availability
