How to build a cloud-based SaaS application?
SaaS or Software-as-a-service is a software distribution model where software is licensed on a subscription basis and applications are hosted by the third party. Nowadays, many software development companies and businesses are adopting SaaS development to compete with their competitors in IT market. We all are aware that SaaS is getting more popular with each passing day and it is attracting more and more commercial enterprises.
SaaS is a relatively small market at $20 billion in total revenues but compared to $250 billion of the overall software market revenue it seems diminutive. It has now grown from nothing to a large extent in the past few years. Similarly, with the eCommerce market, it is also less than 15% of overall revenue. The big trouble is finding the right opportunities where businesses will grow. Meanwhile, there are many experts that are focusing on SaaS alone. Some large enterprises such as Microsoft, SAP, and Oracle are also making their investment to migrate their business from selling licensed software to services.
One of the key opportunities is that ability of small niche markets need to be targeted using SaaS. Since the deployment model, time to value and cost are so much cheaper than the previous time, it is easier to build a niche product that can make a great fan following among the target audience. If it runs and ends up having more budget, it can be a productive market. In SaaS industry, companies are more and more floating application in the cloud. Scaling in the Cloud has some crucial benefits and risks as well. In this article you are going to learn how to start creating a cloud-based SaaS application, dealing with issues of scalability and what this means for your SaaS application?
Everything in the cloud
When building a SaaS application, chances are more that you are developing it in the cloud. The cloud has a lot of benefits- consider scalability –in contrast to local server environments. So, you should focus on software which is assembled and engineered in the cloud. Before starting to make a cloud-based application you must ensure which programming language, database, and software tools you should choose. There are many questions that need to be answered. Here we’ve tried to solve most common & important things.
Which programming language should you choose?
Developing a product for the cloud means developing a product under modern programming language besides abilities and your skills the choice of your programming language will be affected by the possibilities of each language. There are multiple programming languages out there which makes it a difficult task to choose the right one. Take a look at the most popular ones and try to experiment as much as possible. Try to do this using Python.
Python is the most powerful and widely used programming language, and it is designed to specialize on its code readability. Python has framework also for a web application you would like to build. Since I have enough experience with Python before using it for my web app and it’s flexibility for various use case is just another reason to go with Python. It is a great language and supports dynamic typing, Metaprogramming, and rapid prototyping everything can be done easily with Python.
You should include the installation of a database into your list. It is advisable that one should prefer a document-oriented database because these databases are quite different to the outdated concept of the relational database. The document-oriented database gets their type information from the data itself. Therefore, every instance of data can be different from any other which allows more flexibility when dealing with the changes. Since it often reduces the database size, therefore, this concept gives you a richer experience with latest programming techniques.
MongoDB is the document oriented database which offers high performance, better availability and simple scalability and that is the most significant factor for developing a SaaS application. Scaling your technical ability with MongoDB is pretty easy and with automatic sharing features, you can distribute data across the various machines.
A message queuing system is an asynchronous communication protocol which allows the sender and receiver of a message not communicating at the same time. It is also known as Message Queuing (MSMQ) technology as it allows web apps to run at a different time and communicate with the 3rd party integration asynchronously. It limits the size and the amount of data transmitted in the queue.
AWS & EC2
The AWS enables you to host and run your web apps as well performing the high-speed batch job. AWS offers an accessible server for businesses with elastic compute cloud (EC2). The EC2 is a must have a cloud which gives a resizable computing capacity. With EC2 installation it’s very easy to keep adding new server and resources.
Web storage S3
Getting more and more users on board for your product will make you easily surprise about your web storage. With the Amazon S3 storage service, you can have a great and highly scalable installed object storage. S3 is simple, easy to use, store and retrieve the unlimited amount of data. Amazon S3 can also be used with the other 3rd party storage sources and gateways.
Content Delivery Network
A content delivery network (CDN) is simply an arrangement of distributed servers that enables you to serve content to your app users with high performances and availability. If you have 3 EC2 installed at three different location one in the US, second in Europe and the third in Singapore If someone visits your app from New York, the CDN enables you to serve content to the user through the EC2 located in the US.
With Python and MongoDB which is an excellent documented oriented database, the basic setup is executed. Developing a cloud-based application architecture requires not only things you consider, but many of the traditional concepts are still essential, such as sound design, testing, and learning from your own mistake. Learning from your mistake makes you the best in your way to finding a more effective path to build an application in the cloud.
SaaS trends are changing regularly and you have to prepare yourself for the latest updates to stay ahead of your competitors. Customer oriented approach, user friendliness, and effective marketing strategies will help to gain more revenue. SaaS development can be a smart investment for your business.
