Challenges of Software as a Service
The adoption rate of Software as a Service (SaaS) has been dramatic in recent years. Trials of applications like Salesforce. com, WebEx, or NetSuite have transitioned to enterprise-wide deployments, and many organizations have adopted “SaaS first” policies.
However SaaS adoption is not without its challenges. The tendency of SaaS applications to be siloed has made managing user access and authorization an increasing challenge. The task of on boarding users is a time-intensive, manual process that involves administrators across multiple departments, which can introduce risk. Users hate having multiple passwords. Help desks hate multiple passwords too, since users forget them. Managing and synchronizing multiple passwords is expensive and problematic. IT departments must find a way to harness the benefits of SaaS, while minimizing business risk.

Configure a Virtual Private Cloud (VPC)
Amazon Virtual Private Cloud (Amazon VPC) enables you to launch Amazon Web Services (AWS) resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.
VPC with Public and Private Subnets (NAT)
Amazon VPC enables you to launch AWS resources into a virtual network that you’ve defined, called a virtual private cloud (VPC). The configuration for this scenario includes a virtual private cloud (VPC) with a public subnet and a private subnet.
Cloud computing is fast becoming the standard method of creating scalable, manageable web application services, and Amazon is leading the way.

A web app is any software that users access through a web browser or specialized web client. Web apps are typically structured into logical tiers. For example, a common structure uses three tiers. The first tier is the web browser, which is responsible for presenting the user interface. The middle tier is an application server, which is responsible for the application’s functionality. The third tier is a database server or file system, which is responsible for data storage.
With Amazon Web Services (AWS), you can provision compute power, storage and other resources, gaining access to a suite of elastic IT infrastructure services as your business demands them. With minimal cost and effort, you can move your application to the AWS cloud and reduce capital expenses, minimize support and administrative costs, and retain the performance, security, and reliability requirements your business demands.
