Introduction
If you’re like most businesses, you’ve probably spent a lot of time thinking about the cloud but still aren’t sure which type of deployment model is right for your company. That’s because there are so many different types of cloud deployments—and they work differently from each other. Let’s take a look at all the major deployment models and see how they might apply to your business:
Private Cloud
Private cloud is a cloud infrastructure that is deployed and operated exclusively for the organization using it. It can be located on the organization’s premises, or in a demarcated section of the public cloud. Private clouds are often built as an extension of an existing data center, with additional networking equipment and software defined networking (SDN) used to logically segment it from other parts of the enterprise network.
Private clouds give you all the benefits of public cloud plus more control over your data security policies, compliance requirements and application development process–without sacrificing any performance or scalability advantages inherent in public-facing services like AWS or Azure.
Public Cloud
Public cloud is a model of cloud computing in which the cloud provider owns and maintains the infrastructure, while the client uses the cloud infrastructure to run its applications. Public clouds are typically available on a pay-as-you-go basis.
In this model, you do not have any say in what type of hardware or software will be used to host your application–the provider decides based on their needs. This means that if you want to change something about your application (like upgrading from PHP 5.3 to PHP 7) you’ll need to go through them first and see if they’re willing to accommodate your request before making any changes yourself
Hybrid Cloud
Hybrid cloud is a combination of two or more clouds. It’s a good choice for organizations that want to use the benefits of public and private clouds but don’t want to deal with managing them separately. A hybrid deployment is also useful for businesses that need access to some applications on-premises, but most of their data resides in the cloud.
For example, let’s say you have an application running on an Amazon Web Services (AWS) Elastic Compute Cloud (EC2) instance located in Virginia and another running on Google App Engine (GAE) located in California. In this case, it might make sense for both instances to be hosted on your own private cloud instead of sending traffic across multiple regions via internet connections–which could result in slower performance or higher latency issues depending on your network configuration
Community Cloud
Community cloud is a shared pool of configurable computing resources, which are provided as a service to a community of consumers from a common provider. Community cloud is designed to serve the needs of communities of users (e.g., campus communities, businesses within a single industry, or distinct organizations).
Utility Cloud
Utility cloud is a pay-as-you-go model that provides on-demand access to computing resources. In other words, you only pay for what you use and can scale up or down as needed.
Cloud Computing is a utility model like electricity or water: it’s based on the pay-per-use concept with no long term commitment or upfront costs. It’s flexible, scalable and on demand computing service offering the ability to provision resources quickly without having to invest in hardware upfront (e.g., buying servers).
Building a Customized Private Cloud
You can build a customized private cloud by combining both public and private cloud. This is the most popular model for deploying your own infrastructure, especially if you want to take advantage of open source software.
A customized private cloud can be built using either an open source or proprietary software stack. If you choose to develop your own stack, then it will have less flexibility than using an off-the-shelf solution that has been designed specifically for this purpose (such as OpenStack). However, building your own solution gives you more control over performance and security settings because they’re not being managed by someone else’s system administrator team in another location–you’ll have total control over every aspect of deployment!
These are the major cloud deployment models.
The following are the major cloud deployment models.
- Private cloud: A private cloud is a dedicated infrastructure that’s owned by an organization and operated solely for its own use. It can be used to support business-critical applications that require high levels of security and availability, such as those running on mission-critical systems or sensitive data sets requiring compliance with industry regulations.
- Public cloud: A public cloud allows users to rent virtual machines (VMs) or storage capacity from third parties via the internet using pay-as-you-go pricing models rather than purchasing physical hardware and software licenses outright. Public clouds offer IT departments greater flexibility in terms of scalability, speed of deployment, geographic coverage and cost savings compared with traditional on-premises IT solutions because they don’t require upfront costs associated with purchasing hardware or licensing fees before deploying applications into production environments
Conclusion
We’ve covered the seven major cloud deployment models. Each has its own pros and cons, but all of them have one thing in common: they can help you save money on IT costs while getting more out of your resources. Which is why we think it’s worth looking into whether or not one of these approaches would work for your company!
