A lot of SaaS application businesses are now coming into foray.
And it is quite great. Essentially, the SaaS business is vitally a super-fast growing industry that attracts numerous people as well as companies. Such organizations are basically floating application in the cloud. Also, scaling in the cloud has quite a few essential benefits with associated risks as well. Here, we are discussing the platforms for SaaS application development services that can accentuate a business.
Developing for the Cloud
Whenever building a global SaaS app, the chances are quite high that you are developing it in the cloud. As previously said, there are numerous advantages of the cloud, especially scalability, which is in stark contrast to local server environments. Hence, we will be focusing on the software that is built as well as engineered in the cloud.
It starts with which database, programming language as well as software tools you should choose. Let’s go through all of this.
Developing a product for the cloud essentially means developing a product with the most popular and modern programming language. Along with personal skills and abilities, the choice of the programming language will be actually influenced by the offered possibilities of each language. At present, there are numerous modern programming languages which are out there that makes it harder to choose the right one. A SaaS development company needs to make the right choice of programming language.
It is widely utilized programming language which is designed to emphasize on the entire code readability. It can easily do a lot of things certainly. Whichever web app you wish to create, there is certainly a framework for it in the Python programming language. The flexibility of Python for different use cases is another reason for SaaS development service to jump on Python. It is certainly a great programming language which has dynamic typing, rapid prototyping, metaprogramming.
One of the first few things on the list to include is the installation of a database. It is recommended to make utilization of a document-oriented database. The document databases are certainly different from the conventional concept of the popular relational databases.
Choosing Document-oriented Database
Such databases get their entire type of information from the data. Hence, every instance of data can be quite different from the other. It allows much more flexibility, especially whenever dealing with the changes. Also, it reduces database sizes. The DOB concept provides a much richer experience with most of the modern programming techniques. Software design services often choose a document-oriented database for web apps.
MongoDB is essentially a document-oriented database which offers high availability, high performance as well as easy scalability. Besides performance, the scalability is the most crucial factor for any global SaaS business. A large number of SaaS founders actually aim for scaling their entire business. Hence, besides scaling the product from a particular business perspective, one shouldn’t forget about the different technical matters. Scaling the tech with MongoDB is quite easy. With the automatic sharding, one can distribute the data across different machines. Sharding is essentially a method for storing data across different machines. MongoDB utilizes sharding to support the deployment with much larger datasets.
Setting up MongoDB for the SaaS app
To get started with the MongoDB, you can install a single MongoDB instance for the AWS EC2 instance. With the increasing number of customers, you will notice performance issues in different areas of the world. Hence, install a master/slave architecture with the master at one place and two MongoDB slave instances in the other place. These two slave DBs use read preference in order to avoid queries across the globe to readily keep the network delay for frequent and regular read operations as low as possible. Also, the writes still go directly to the entire master DB and then get replicated to the slaves by MongoDB automatically.
The Queuing System
Now it is turn to learn about the queuing system. Essentially a message queuing system is simply an asynchronous communication protocol that allows sender as well as the receiver of the message not having interaction at the same time. Termed as Message Queuing or MSMQ technology, basically, it enables the web applications to run at various times and even communicate with the different third-party integrations, APIs or even other services in an asynchronous fashion. A message is essentially placed onto the queue. Also, it is stored there until the message receiver retrieves it. A message queue also has limits concerning the size as well as the amount of data transmitted in the entire queue. The best thing about the modern queuing system is that it can easily be scaled. A custom software development company should use the most robust modern queuing system.
One of the most used queuing systems is RabbitMQ. It is essentially a robust open-source queuing system that runs on all of the major operating systems. You can run a web app in easily on the AWS EC2 where this queuing system can easily be installed and run highly smoothly.
The programming language, Python, along with celery task management library which is open source, is the best fit to get the most out of this queuing system. It is quite important to have a well-proven and robust software at this point as it actually builds the backbone of the entire infrastructure.
Utilizing a single RabbitMQ server, along with multiple endpoints which feed the entire queue with different tasks along with endpoints which process those particular tasks is seamless. Also, the optimal configuration would generally include a second RabbitMQ server in order to provide replication as well as failover mechanisms.
AWS & EC2
Developing a scalable web app will often end up at utilizing Amazon Web services way sooner than expected. It enables you to easily host as well as run the web apps along with performing massive high-performing batch jobs. Through Elastic Compute Cloud or EC2, the AWS offers scalable virtual servers along with cloud integration solutions for all sorts of business.
Why choose EC2?
Basically, the Amazon EC2 remains to be the heart of the system which offers resizable computing capacity. One can rent virtual servers on which the cloud-web app runs. Also, the best thing is that these EC2 servers are actually spread all over the world. So, depending on the need to readily scale and which particular geographical market to target initially, you can easily select between different locations of the EC2.
At present, there are multiple EC2 servers at different locations, and you can keep adding further locations as the demand for your product keeps on increasing. Also, with the installed EC2, it is quite easy to add new servers as well as resources. CRM development services are rapidly adopting EC2 for web apps.
Web Storage S3
Obtaining more users on board of the product will make you wonder about the web storage. Hence, with the Amazon S2 storage services, you are provided with highly scalable object storage duly installed. The Amazon Simple Storage Service or the S3 is quite easy to utilize, store and even retrieve any volume of data. However, Amazon S3 can not just be used with other AWS services but also with third-party storage gateways and repositories. It works perfectly well with EC2. Also, storing the data of web app with S3, you can easily create backups, big data analytics and archives.
CDN or Content Delivery Network
Essentially a CDN or content delivery network is a system of different distributed servers that enables you to serve content to the application users with high availability and high performance.
With the assistance of MongoDB, a robust document-oriented database, Python and RabbitMQ, the basic setup is duly done. However, there are certainly different ways to achieve this. You can also inculcate proper monitoring as well as analytics software along with payment procedures which can run smoothly in the cloud.
