You'll find a collection of simple All-in-one ServerTemplates in the MultiCloud Marketplace, which are useful for new RightScale users and basic demos. Use one of the All-in-one ServerTemplates, such as the LAMP (Linux, Apache, MySQL, PHP) ServerTemplate to launch a single server that contains a web server (Apache), as well as your application (PHP) and database (MySQL). The architecture diagrams below show a progression from simple to more complex reference architectures. Security - For MultiCloud system architectures, it's important to realize that cross-cloud/region communication is performed over the public Internet and may introduce security concerns that will need to be addressed using some type of data encryption or VPN technology.Since ServerTemplates are cloud-agnostic, you can use them to build portable cloud architectures. Cloud Portability - Although it might be easier to use one of the cloud provider's tools or services, such as a load balancing or database service, it's important to realize that if and when you need to move that particular tier of your architecture to another cloud provider, you will need to modify your architecture accordingly.For example, do you need an instance type that has high memory or high CPU? From a geographic point of view which cloud will provide the lowest latency for your users? Is it necessary or cost effective to use a content distribution network (CDN) or caching service? For user-intensive applications, the extra latency that results from cross-cloud/region communication may not be acceptable. For example, you could launch different instance types based on your application's needs. Speed - The cloud gives you more flexibility to control the speed or latency of your site/application.For example, a system architecture that is distributed across multiple clouds (regions) introduces complexity at the architecture level and may require changes at the application level to be more latency-tolerant and/or be able to communicate with a database that's migrated to a different cloud for failover purposes. A more complex solution should only be used if a simpler version will not suffice. Simplified architectures will always be easier to design and manage. Complexity - Before you construct a highly customized hybrid cloud solution architecture, make sure you properly understand the actual requirements of your application, SLA, etc. For example, in AWS, data transferred between servers inside of the same datacenter (Availability Zone) is free, whereas communication between servers in different datacenters within the same cloud (EC2 Region) is cheaper than communication between servers in different clouds or on-premise datacenters. There are different costs associated with both private and public clouds. Cost - Before you architect your site/application and start launching servers, you should clearly understand the SLA and pricing models associated with your cloud infrastructure(s).There are several factors that you need to take into consideration before designing your own cloud-based systems architecture, particularly if you're considering a multi-cloud/region architecture. Get more details and additional reference architectures in our white paper: Build Scalable Applications in the Cloud: Reference Architecture & Best Practices. When you are designing your own solution architectures you should consider integrating several of the concepts described below. The diagrams are designed to demonstrate a particular concept such as disaster recovery or multicloud deployments. Once you find a system architecture that is similar to what you are trying to build, you can modify and customize it accordingly to meet your own project's requirements. The purpose of the system architecture diagrams below is to provide you with real-world examples that you can use as base reference architectures when you design your own custom system architectures in the cloud. Most of these architectures can be built using existing ServerTemplates that are available in the MultiCloud Marketplace.Įach application is unique and will have a custom set of requirements. Below you will find several sample diagrams of cloud-based solution architectures that you can build with the RightScale platform using both public and/or private cloud infrastructures.
