In today's ever-changing economy and lifestyle, nearly every aspect of the tasks we do is driven or guided by technology. Advancements have fast-tracked the way we all apply time and resources. As a developer, you need tools and resources to work through the challenges and achieve milestones.
Any project has prerequisites that require a well-defined software development lifecycle (SDLC). A properly structured and strategized SDLC can administer productivity and accelerate project success.
Whether you are a developer or a team-strategist, you need to keep yourself updated with the latest tools, trends, and practices of the industry.
There were times where hosting an application or a standard website was a tedious process. With limited options for domain and hosting space providers, the time-era cost to yield ratio was very low. The costs were high, and the yields were low. Outright reaching customers, developing web applications for specific tasks, and optimizing everything for search engines was practically non-existent.
Business applications were considered to be a feat for a handful of software giants.
The cloud computing era has changed the way certain tasks are handled. The customer-centric solution and reach have made way for an immersive experience altogether. With further advancements in cloud computing, where more viable cloud services providers, like Alibaba Cloud, took to the challenge of evolving the whole cloudscape by introducing task-specific tools and services. With these services, the industry achieved Low Cost – High Yields.
These managed services are backed by tools that are seasoned and tested. Services, such as Web+ and the Simple Application Server (SAS) have revolutionized the way developers and administrators strategize product deployment.
Alibaba Cloud provides different tools and services based on Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Let's take a look at the image below learn more about the basic variance:
Simple Application Server is a service that delivers easier experiences for developers and administrators. It offers a one-stop-answer to all of the queries related to building a private server.

What can you use it for?
The structure graph below will shed some light on the workflow of SAS:
Using the Simple Application Server, you can:
The Alibaba Cloud Simple Application Server (SAS) offers numerous pre-installed application and system images including:
The application images include the application, configuration data, runtime environment, and operating system. The system images only contain the operating system. The Simple Application Server (SAS) makes it a matter of clicks for you to deploy any pre-installed image and get on with your work. Similarly, with operating system images, all you are required to do is to account for which applications you wish to use and install them to get to production.

These I/O-optimized shared instances account for resources like CPUs, memory, OS, storage, network, and other resources required for the application server to work. When it comes to storage, SAS uses the high performing SSD storage for better response time and reliability. Alibaba Cloud's Virtual Private Cloud (VPC) ensures a safe and reliable network.
The Simple Application Server integrates support for domain name resolution, HTTS encrypted access using CA certificate, and a Virtual Private Cloud.
