Cloud Deployment Models

Cloud computing and Deployment Models

Cloud computing is a system that provides individuals or businesses with services through the internet. Organizations often use clouds to easily store, transfer and update their company data. Since users access their cloud services online, the cloud can make it easier for companies to allow their employees to access business resources from a variety of locations and devices. Clouds can also provide many other services in a virtual environment, including servers, databases, software and networks. There are various cloud computing deployment Models in practice.

Let us have a look into a few of them which are more commonly used.

• Private Clouds
• Public Clouds
• Hybird Clouds
• Multi Clouds

Private cloud model

A private cloud (also known as an internal cloud or corporate cloud) owned and used by single private businesses and organisation. It is a single tenant environment. The organisation using it (the tenant) does not share resources with other users. Those resources can be hosted and managed in a variety of ways. The private cloud might be based on resources and infrastructure already present in an organization’s on-premises data center or on new, separate infrastructure, which is provided by a third-party organization. In some cases, the single-tenant environment is enabled solely using virtualization softwares like VMware and Citrix.

You have complete control over the infrastructure, you can create your cloud computing approach to your own preferences and internal processes. Some of the more stringent security and compliance on certain types of data and resources can be kept inside your own security boundary. It is the most secure option because the organization has direct control over the infrastructure and only authorized users can access the network.

High Lights

• Complete control over all the components like infrastructure, Data, Security, Access.
• Owned by single entity
• Own Process.
• Increased security
• Increased Performance.
• Customisable as per requirement.
• No cost for unused components

Low Lights

• Cost of setup is high
• Maintenance cost increases over a period of time
• Need specific skill set to manage the infrastrcutre
• Utilization of resource is very less.

Public cloud deployment models.

A public cloud is a platform that uses the standard cloud computing model to make resources such as virtual machines, applications and storage available to users remotely. Public cloud services may be free or offered through a variety of subscription or on-demand pricing schemes, including a pay-per-usage model.It is an model where on-demand computing services and infrastructure are managed by a third-party provider and shared with multiple organisations using the Internet. These service providers may offer cloud-based services such as infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (Saas) to users for either a monthly or pay-per-use fee, eliminating the need for users to host these services on site in their own datacenter.

Public cloud makes computing resources available to anyone for purchase. Multiple users typically share the use of a public cloud. In contrast, private cloud involves cloud-based services that are hosted within an organization’s own private servers.The public cloud is also a popular solution for storage needs since data stored on a public cloud is backed up and accessible from anywhere. There are many different types of storage plans, and data that does not need to be accessed frequently can often be stored in the public cloud very cheaply.

Highlights

• Scalability
• Easy to use
• Plug and play
• High Availability
• Word wide network access
• Huge resource power
• Computing power
• Pay per use model

Low Lights

• Service disruptions
• Low Internet bandwidth locations.
• Security limitations
• Data regulation security
• Risk tolerance of consumer.
• Running cost
• Low control over underlying infrastructure.

Hybrid cloud deployment models

Hybrid cloud refers to a mixed computing, storage, and services environment made up of on-premises infrastructure, private cloud services, and a public cloud such as Amazon Web Services (AWS) or Microsoft Azure and google GCP. A hybrid cloud approach is one of the most common infrastructure setups today because you can continue to use your on-premises servers while also taking advantage of public cloud.

Highlights

• Application management and control
• Performance improvement
• Latency decrease
• Operational flexibility
• Cost optimisation.
• Compliance

Low Lights

• Local Infra management cost
• Technical resource.
• Cost of maintenance.

Multi Cloud Deployment Models

With Multi Cloud deployment models, you can easily sync two cloud services or two folders on different cloud accounts. You can also set up scheduled sync to sync your data between clouds at a certain interval automatically. This is mainly used because the companies don’t want to depend on one single provider. So there is one more backup solution they have. This removes the dependability on a single provider.

A multi-cloud service standardizes one or more functional areas across clouds with a consistent API, object model, identity management and other core functions and has one or more of the following characteristics:

• Runs on a single cloud but has comminications with at least two different clouds
• Runs on multiple clouds and has communications with at least two different clouds
• Runs on a cloud or edge of a user’s choosing, even in disconnected mode, and basic operations are fully automated

Highlights

• Multiple vendors.
• Less dependency on provider
• Consume best from each provider
• Distributed work force

Low Lights

• Resource requirement for management
• Complex design
• Security boundary.
• Higher cost of using multiple vendors.
• Data boundaries.
• Network constraints.
• Different landscape.

Once you have finalised in on which Cloud computing Deployment Models that suits your organisation and the next step will be to look into the cloud service model. The deployment model tell you how to distribute and manage the underlying infrastructure like the servers, storage, and networks. The Service model will help you to differentiate the layers of service that is required for you. So you are ready with the first step in the journey to cloud adoption. The cloud has changed drastically over the years. At first, it was just an exotic option without many variations. Today it comes in many models and kinds , and it is even possible to create your own private cloud in your data center.

There are so much of details and data related to cloud but again it comes backs to the consumer to decide wise. So choose wise and have a happy cloud journey.
