At the start of internet revolution, developers made software which was installed at client’s system, and the client based app accessed the server and its resources to run the applications. Web applications eased the client server based transfer of messages and data. It provided services to user to access applications through different platforms.
Now a day, web applications are independent of the programming language and platform. It can be accessed from any machine and are compliant with different types of devices.
Progressive web application
The newest breed of web applications are progressive net app built on modern browsers for mobiles, offering services as traditional websites.
Progressive web applications are Microsoft and Google supported concepts, based on reducing gap between native app and the web app.
Twitter has been developing such applications and its wider adoption reduced the need for the installation of supportive phone SDK, tools and languages.
Risks and Security
Security is a key feature where the organizations are trying to protect data from internet based threats. It is necessary to prevent vulnerability and to fix issues. To secure an app, firewall is installed by the user but such network based security is not sufficient. These days the attackers can enter the client server system through browsers.
Securing the browsers
Databases of most of the companies are kept at cloud and most systems rely on browsers for handling user based risks. Attackers can get into the area through reverse engineering and understand the programming logic or mechanism of communication. It is necessary to secure the client side as well, as it can be breached by the intruders. The client side security systems can provide security to prevent damage to brand image, intellectual property, government penalties and loss.
Some organizations apply the remediation process where patch management can be used to mitigate vulnerability. Most cases of hacking, up to 81 per cent, involve weak passwords, and hence, the use of strong password is promoted. Further, infrastructure security is needed to deploy firewalls properly and prevent losses.
Application security testing and developer training is also significant in this regard.
Micro service architecture
Many new apps are built on micro service architecture where it involves individual modules built and tested, separately, in parallel. Such smaller units help to create lightweight apps, and improve speed of delivery of services. It also provides portability and productivity.
A small change in a monolithic app may require change in each part of the application code but in case of micro service based app the changes in one unit, can be implemented to all the others.
To load a monolithic app, the whole app has to be closed and restarted but for smaller code units, one may not need to close down the whole system to restart. Such systems can be updated by updating a part of the whole unit.
