Deployment models for cloud computing

When selecting a cloud strategy, a company must consider factors such as required cloud application components, preferred resource management tools, and any legacy IT infrastructure requirements.

The three cloud computing deployment models are cloud-based, on-premises, and hybrid. 

Select each tab to learn about each category.

 

• Cloud-Based Deployment
  
  •  
  • Run all parts of the application in the cloud.
  • Migrate existing applications to the cloud.
  • Design and build new applications in the cloud.

 

• On-Premises Deployment
  
  • Deploy resources by using virtualization and resource management tools.
  • Increase resource utilization by using application management and virtualization technologies.
• Hybrid Deployment
  
  • Connect cloud-based resources to on-premises infrastructure.
  • Integrate cloud-based resources with legacy IT applications.
   

Benefits of cloud computing

Consider why a company might choose to take a particular cloud computing approach when addressing business needs.

• Trade upfront expense for variable expense
  • Upfront expense refers to data centers, physical servers, and other resources that you would need to invest in before using them. 
  • Variable expense means you only pay for computing resources you consume instead of investing heavily in data centers and servers before you know how you’re going to use them.
• Stop spending money to run and maintain data centers
  • Computing in data centers often requires you to spend more money and time managing infrastructure and servers.
  • A benefit of cloud computing is the ability to focus less on these tasks and more on your applications and customers.
• Stop guessing capacity
  • With cloud computing, you don’t have to predict how much infrastructure capacity you will need before deploying an application. 
• Benefit from massive economies of scale
  • By using cloud computing, you can achieve a lower variable cost than you can get on your own.
• Increase speed and agility
  • The flexibility of cloud computing makes it easier for you to develop and deploy applications.
• Go global in minutes
  • The global footprint of the AWS Cloud enables you to deploy applications to customers around the world quickly, while providing them with low latency.
    • Network latency, sometimes called lag, is the term used to describe delays in communication over a network.
