Building Large-Scale Web Applications
The scalability and flexibility of the applications are critical factors considered when building large-scale web applications. Let us understand and deep dive into it.
Speed and performance are the critical factors considered when building large-scale web applications. The scalability and flexibility of the applications designed by web developers have an important role to play as it defines the usage statistics and performance of the web applications. Load balancing is what these applications must work on in an efficient manner as it’s the crux of multiple users using the application at a particular time frame without potential lags and technical glitches. The quality of operations and activities shouldn’t degrade at any cost should be the primary aim of any web developer developing a large-scale web application.
Let us understand and deep dive in what are the best practices to build large-scale web applications.
Few characteristics of large-scale web applications are enlisted below:
- High performance - large volumes of data transactions are handled by large web applications with ease unaffecting the overall speed and performance.
- Varied types of data - These applications handle varied types of data such as logs, customer records, products, and many more.
- Availability - It is available round the clock irrespective of the maintenance downtime which is informed in advance to the user community.
- Data distribution - The data distribution across these large-scale web applications is simply awesome. They are distributed across servers in either various data centers or on cloud premises.
In addition to this article also shares the best-suited frameworks for large-scale web applications which are Laravel, Angular JS, ASP Dotnet, React JS, Node JS, and Codelgniter.
Best techniques for load balancing while building large-scale web applications:
Equal distribution of data across various routers available on the architecture that help replicate the front-end web applications. DNS (Domain Name System) load balancing, HTML redirection, and load balancing switch are the practical techniques for implementation of load balancing:
- DNS (Domain Name System) load balancing:
- Mention more than one target for a single name
- DNS servers rotate and circulate among those targets
- HTTP redirection (HotMail, now LiveMail):
- The front-end machine approves and considers the initial connections
- Once the initial stage is accomplished it will redirect to back-end servers
- Load-balancing switch:
- All incoming data packets parse through one load-balancing switch which is then dispatched to the respective server
- Inspection of the data is at times done as this load-balancing switch before distribution of data packets to the various servers
On reviewing the steps to build Large-Scale Web Applications: Business requirements should be treated as the backbone for any web design and web development. The planning phase involves communication which must be clear and crisp in terms especially of deadlines and expenses. Stakeholders should also have a clear picture on what are the required steps to achieve the business goals and should be aware of the potential challenges. A quick checklist of questions to be answered while web design and development.
- Number of users involved
- The time frame of release
- Server configuration settings
- Backup or Recovery plans
Let us now focus on the scalability of the system and web applications: Almost all web applications have started using Real-time databases. Partitioning and compression of the memory and databases are the new norms. There is a paradigm shift from using traditional databases to main-memory caching. Main memory caching (Memcached) stores keys and data values as arbitrary blobs which are termed as key-value storage. This not just speeds up performance but also improves scalability.
Although there are various issues raised while scaling web applications. It also makes web applications disastrous if scalability is not implemented correctly. Datacenter management and installation of new servers are some of the tedious tasks involved which take time and have business risks involved. PaaS is a cloud computing model that supports and helps in the implementation of scalability.
What are the best practices to build Large-Scale Web Applications?
- Selection of correct tool
- A right data loading mechanism
- Multi-level caching
- Use async communication
- Automation techniques
- Testing of the web application before release
- Multiple databases storage are to be preferred for data consistency and integrity
- Apt web design framework for web application development
Handling data is also an art and the following are the tricks to handle data sessions:
- Redirection of different data packets on different servers
- The probability of Stand-alone servers crashing is maximum
- Take or arrange sessions to redirect and move data to the respective assigned server
- Possible solutions or alternatives are:
- Solution1: Store session storage in shared storage either the file system or database In addition to this the retrieval of data requests is costly.
- Solution2: To keep session data in the cookie and set the cookies limit according to the session data.
- Solution3: Cached session data is used at the last in case of storage is insufficient in the file system or database. Also if the future request goes to a different server, mapping of data is to be done.
If the business requirements are such that scalability is the primary focus of web development then it is important to have a partnership with a web development company that can endow not just their technical expertise but have business foresight. A web development company that knows what are the best practices to build Large-Scale Web Applications. Hiring a dedicated team of web developers comprising of IT architects, web designers, and end-to-end project implementation experts is always beneficial.
