The Ideal SaaS Development Platform and Amazon Web Services

Software development is better for most SaaS companies since product cycles are shorter, overall costs are reduced, and the technology is more current than any other. Existing software companies opt for their existing systems but one needs to opt for modern web technology to grow better while improving their ability with multi-tenant, web-centric software. Companies are required to evolve from legacy technologies including Adobe Flash, Microsoft Silverlight, and Windows Presentation Foundation (WPF) for embracing newer technologies of the future - HTML5, CSS3, and jQuery.

It is seen that bad software architecture is much more visible in SaaS products than the desktop ones. It has been evident that users find that some platforms do not scale well when run with multiple tenants on a simultaneous basis. Horizontal scaling might be possible, but one needs to be wary of inefficient use of resources which can amount to incredible cost of providing SaaS services. Developers need to know about the latency issues which might result in poor performance on public clouds. Security is extremely important to the architecture since there are simultaneous users on the shared platform protected by a single firewall.

The SaaS architecture requires itself to be absolutely fast, secure, and easy to use with an efficient data services layer. SaaS products need to consist of APIs for allowing development of some add-on capabilities. The published APIs are required to be dependable and standard and need to be maintained well.

Stateless designs for SaaS require well-organized storage services like Amazon’s Simple Storage Service which is not local to any single server and can be accessed through (RESTful) APIs. In the event when there is a server failure, the software managing the system will spring up another instance for replacing the failed compute instance with ready accessibility to data in the cloud infrastructure. The virtual server instances which are not required will be released and the app is then connected with another server instance at its next interaction.

The public cloud infrastructure does not offer support the bandwidth for storage virtualization without performance ramifications and plan. SaaS systems generate huge data which drive data analytics processes and hence the locality of both need to be the same SaaS companies are being more innovative nowadays and do not rely on software maintenance as before. Hence the users are in an advantageous position of getting to know about present innovations easier. Here SaaS companies need to be extremely careful that there should be no disruption to the customer’s environment. Software uptime is extremely critical and any downtime can affect a company’s fortunes. The backup needs to be resilient from failure.

Software upgrades are extremely complex since there should be no downtime and less maintenance window. There are mostly lengthy operations required for a software update. The cloud model helps in keeping the new release fully functional and running on the independent server before moving any tenants. Also the process of SaaS restructuring is quicker than the upgrade process which is time-consuming and might even cause unnecessary downtime.
