8 Ways to optimise application performance using microservices

There is an undeniable demand for Microservices these days. Now every software community, application groups, and business units focus on faster functionality rollouts, more frequent updates, and capability for development groups to deliver independently.

There is an undeniable demand for Microservices these days. Now every software community, application group, and business unit focuses on faster functionality rollouts, more frequent updates, and capability for development groups to deliver independently.

The most common problem these days is that several new technologies are discovered without considering the scalability, testing, server load, and so on. This results in issues when something is created using new technology when sent into production and is attacked by external malefactors.

Here we take a look at several practices which you need to consider microservices for improving your app performance

1. Faster distribution of important security patches

You might be coming across several articles about the breaches at major enterprises stating unapplied security patches as a reason why a particular vulnerability was destroyed by hackers. It is a fact that lagging patch distribution is a major issue, very much that there are specific products that allow security patches to be enabled with virtual patching unless the patches can be applied to running systems.

Ultimately, microservices can make patch deployment much easier and faster. Many enterprises integrate DevOps frequent release cycle along with microservices, instead of releases happening once or twice a year they can happen several times a week as well.

This indicates that important updates can protect systems in comparison to the past.

2. Smaller Attack Surfaces

The important element of microservices that each service provides a particular set of functionality. Some developers named it as do one thing and do it well. Ultimately, each service reveals a well-structured interface. After all, if the service is asked to do one thing, then only one interface is needed to support that.

3. Simpler code structures

Another issue with the monolithic applications is that it’s hard to know exactly what’s there in the software executable. It means that one group’s security issue may have complications for another group’s code contribution and that group might not know about that.

Microservices can help resolve this issue because the code is divided into particular executables. In enterprises, it is common to take full responsibility by a single development group for all the code running in individual service. So it’s much easier to have peer collaboration within a small group that works on a common codebase than it is to have collaboration among several teams in a huge, monolithic codebase.

4. Functionality Shielding

Another benefit of microservices is the way it handles a defense-in-depth strategy. Rather than having all the functionality deployed in the Front-line service, microservice spreads the functionality. The rest of the application functionality resides in other services that can only

be accessed by other application executables. This protects application functionality from attackers and makes it hard for them to access the non-user-accessible functionality.

5.  Accelerate and protect applications with a Reverse proxy server

If the web application runs on a single machine, then remedy for performance issues might be obvious. You need to get a faster machine with more RAM, more processors, and so on. The new machine can run on any server faster than before.

Problem is, system speed might not be the case. Web apps run slow because the system is shifting to different kinds of tasks: communicating with users on thousands of connections, running application code, accessing a file from disks along with other tasks.

The app server might be crushing down – switching chunks of memory out to disks, running out of memory, and so on.

A reverse proxy server is situated in front of the machine running the application and controls internet traffic. The reverse proxy server is only connected to the internet; communicating with the app servers with a fast internal network.

6. Try adding a Load Balancer

A load balancer is a great technique to improve app performance with microservices and the security of your website. Rather than opting for a core web server bigger and powerful, you can implement a load balancer to distribute the traffic across a number of servers.

In spite of having an application that is poorly written or faces scaling problems, a load balancer can improve the user experience without any further changes.

7. Cache Static and Dynamic Content

Caching improves app performance by delivering content faster to clients. Caching involves processing content for fast delivery, storing content closer to users, and processing content on faster devices.

Caching is categorized into two :

Caching of static content: Files that are changed less frequently such as JPEG, PNG files, and code files ( CSS, JavaScript ) which can be kept on edge server for fetching quicker from the memory.

Caching Dynamic Content: Several web apps generate fresh HTML when a page is requested. If you cache one copy of generated HTML for a short period of time, then you can drastically reduce the total pages that have to be generated while delivering fresh content which will meet your requirements.

8. Compress your Data :

Compression is a major performance accelerator. They are engineered very carefully and highly effective compression standards for pics(JPEG & PNG) and videos (MPEG-4) and music (MP3). Text data includes HTML, CSS, and code such as JavaScript is often transferred uncompressed. Compressing these formats of data can have an unequal impact on web app performance, particularly for clients with slow mobile connections.

SSL compression reduces the volume of data that has to be SSL-encoded, which cancels out the CPU time needed to compress data.

Bottom line :

The performance improvements for web apps vary drastically, and it primarily depends on your budget, invested time, and gaps in your existing implementation. We believe that it won’t be long until security groups are persuading development organizations to microservice app designs. We expect that security professionals will insist on microservice applications for every organization.

It requires a careful approach, planning, and intense technical expertise to take your performance improvement using microservices to your web and mobile application. We Fortunesoft gives you Microservices Solutions by considering Microservices Architecture to streamline both client and engineer experience and build interactive, scalable, and reliable web and mobile applications for you.
