If we look at PAAS in depth, there are a number of application PAAS services offered by different cloud providers
Great thing about these managed services is that the cloud provider would take care of most non functional requirements.
AWS provides RDS - Relational Database Service. A good examples are the database management services provided. PAAS Examples are Managed Services provided by different cloud providers. The cloud provider is responsible for Platform Upgrades, Runtime Upgrades and OS Upgrades. You are only responsible for your application deployable unit. AWS calls them EC2 (Elastic Compute Cloud)Īpproach 2 is called PAAS - Platform as a Service. The virtual servers are also called differently in different clouds You are responsible for installing OS, OS Upgrades, Installing Runtime, Runtime upgrades and everything that goes along with them.ĭifferent clouds provide different IAAS Services. The cloud provider is responsible only for providing the virtual servers. You are getting the infrastructure from the cloud provider and deploying the applications the usual way you do. Approach 2 - You can use a service provided by AWS - for example, AWS Elastic Beanstalk - to deploy your application and not worry about the virtual servers.Īpproach 1 is typically called IAAS - Infrastructure as a Service. Approach 1 - You can create virtual servers (EC2 - Elastic Compute Cloud) and deploy your applications to the virtual servers. You have an important choice to make.ĭo you want to deploy your applications the same way you deploying while using your data center or do you want to use facilities provided by your cloud provider?įor example, if you are using AWS (Amazon Web Services), you have two options However, to have high availability and low latency for end users, you would need to have multiple deployments around the world.Ĭloud Providers make it easy for you to have multiple deployments of your application across the world. It would be difficult for businesses to set up such wide spread infrastructure. Why not leave the “Undifferentiated Heavy Lifting” to the cloud providers? Improved Latency and AvailabilityĮach of the cloud providers have multiple data centers available in multiple continents and multiple countries. 
If business focus on automation, tools and infrastructure, the focus shifts from their core job. To create amazing solutions and provide great service to their customers. You can provision and release resources on demand. If you provision infrastructure in your data center for peak load, then what would it be doing during the rest of year? Sitting Idle! Load during peak season like holidays might 2-10 times the regular load. If you are amazon or a startup, the load on your application varies a lot during the year. Let’s start with understanding why we need the cloud. That’s the kind of courses that we would be talking about in the article. How about deploying these applications to different cloud platforms? When we talk about the Java Spring Boot world, typically we talk about One of the best option to learn the cloud is to deploy some of the applications that you have developed to different cloud providers.
