According to the Market Research Future report, the application modernization services market is expected to reach USD 24.8 billion by 2030, growing at a CAGR of 16.8%. Nobel technologies and improved applications are two driving factors of this growing market size. On one side, it is growing, and on another side, it is failing also. According to this report, unclear project expectations are the biggest reason behind its failure.

That’s why app modernization is a big decision for your organization and business expansion. To avoid failure, you must prepare a list of good questions before planning the app’s modernization. Read the full article to understand a brief of app modernization, its need cum benefits, and questions which could help in designing the best app modernization strategy.

What is App modernization?

App modernization replaces or updates existing software, applications, or IT infrastructure with new applications, platforms, or frameworks. It is like an application upgrade on a period to utilize the technology trends and innovation. The primary purpose of app modernization is to improve the current legacy systems’ efficiency, security, and performance. The process encompasses not only updating or replacing but also reengineering the entire infrastructure.

Need/Benefits of App modernization

Application modernization is growing across industries. It meant it became an essential business need. Here are points which are highlighting that why you need the app modernization for your business:

• To improve the business performance
• To scale the IT infrastructure to work globally
• To increase the security and protection of expensive IT assets
• To enhance the efficiency of business processes and operations
• To reduce the costs which happen due to the incompatibility of older systems with newer technologies

10 Questions need to consider before planning the app modernization

Before designing the add modernization strategy, you need a list of questions according to your business objective and services. Here are questions that might help you to make a proper plan for app modernization:

1. What is the age of your existing legacy business applications?

You have to understand your existing IT infrastructure and resources. How it is working and performing in the current environment. Are they creating problems or running smoothly? Are they causing downtime often? If they are too old, you need to replace everything; although if you upgrade them regularly, check which resource needs to modernize.

2. What are the organization’s current technical skills and resources?

You have to analyze the existing team and experts and understand whether they can adapt to the new infrastructure. You have to know their capabilities regarding learning new applications. In case you did modernization without analyzing your existing team’s capability, but after some time, you find that your experts are facing issues while working on the new IT environment. Thus, knowing the current technical skills and how you would train them for the transformation is good.

3. Would you be willing to conduct a Proof Of Concept (POV) to verify the platform’s functionality?

Are new system features able to solve the problems, and are they beneficial for business? You need to perform POV to check the new system’s functionality and find out how it works. POV can help you to examine the essential features and other characteristics of modernized apps.

4. Can the new system be easily modified to meet the business’s and customers’ changing needs?

Business needs and customer demands are not static. You know it, and it changes as soon as technological advancement or regulatory changes happen. It would be best if you found out that an application would be able to adopt the changes to fulfill your business requirements.

5. How have you surveyed the market and decided on the appropriate platform(s) to execute essential modernization?

You must research the market and list all vendors offering the services you seek for your application modernization. Analyze all factors before finalizing the best platform and services aligned with your objective.

6. How secure are the applications currently?

You have to find the security level of your legacy applications. Because modern apps need high levels and advanced security systems. Old security practices on modern apps might fail your project, so better to check the existing security.

7. Assess the opportunity costs and business risks associated with avoiding modernization?

If you avoid the app modernization, how many business opportunities might you lose, or how many risks might you face? If you escape them, you might face many losses. As discussed, modernization is a business priority in this futuristic technology era. So, be sure to understand its importance on time and execute it as soon as possible.

8. What type of modernization are you seeking?

You need to know the flexibility of your decision regarding app modernization. In simple words, which kind of modernization are you looking for in your business progress? Are you looking for a permanent or a system that could be altered in some years?

9. Did you consider the cloud when designing your application?

Running applications and managing the whole IT infrastructure on the cloud is a business priority. If your legacy applications are not compatible with the cloud, you must understand how you can make them cloud compatible. By doing this, you can easily migrate and modernize your applications to the cloud.

10. Determine what integrations are required to modernize the app?

With modernized applications, you must know the required integrations among hardware, software, or other IT assets. This answer will help you locate the best and ideal platform for your business process execution.

Forbes Councils Member Yasin Altaf has pointed out four factors – evaluate technical and business challenges, assess the current state of the legacy system, find out the right approach, and plan in his recent article. Besides being the leading voice in emerging enterprise technology, Infoworld has also revealed that time and proper tools are key drivers of the app modernization success in this report. In addition, giving time to develop and plan is the best way, according to 36% of IT leaders.

What’s new in AWS Kinesis?

Amazon Kinesis Data firehose now also supports dynamic partitioning, where it continuously groups in transit data using dynamically or statically defined data keys and delivers the data into the individual amazon S3 prefixes by key. This reduces time to insight by minutes, it also reduces the cost, and overall simplifies the architecture.

Working with Streaming Data

For working with streaming data using Apache Flink, we also have AWS kinesis data analytics service, as with Amazon Kinesis Datastream like Kinesis Data Firehose, this service is also a fully managed, serverless, Apache Flink environment to perform stateful processing with sub-second latency. It integrates with several AWS services, supports custom connectors, and has a notebook interface called KDA Studio (Kinesis Data Analytics Studio), a managed Apache Zeppelin notebook, to allow you to interact with streaming data.

Similar to Kinesis Data Analytics for Apache Flink, Amazon managed stream for Apache Kafka or MSK is a fully managed service for running highly available, event-driven, Apache Kafka applications.

Amazon MSK operates, maintains, and scales Apache Kafka clusters, provides enterprises with security features and supports Kafka connect, and also has multiple built-in AWS integrations.

Architecture for Real-Time Reporting

Here we derive insights from input data that are coming from diverse sources or generating near real-time dashboards. With the below architecture what you are seeing is, that you can stream near real-time data from source systems such as social media applications using Amazon MSK, Lambda, and Kinesis Data Firehose into Amazon S3, you can then use AWS glue for Data Processing and Load, Transform data into Amazon redshift using an AWS glue developed endpoint such as an Amazon Sagemaker Notebook. Once data is in Amazon Redshift, you can create a customer-centric business report using Amazon Quick sight.

This architecture helps in identifying an act on deviation from the forecasted data in near real-time. In the below architecture, data is collected from multiple sources using Kinesis Data Stream, it is then persisted in Amazon S3 by Kenisis Data firehose, initial data aggregation, and preparation is done using Amazon Athena and then stored in the AWS S3. Amazon Sagemaker is used to train a forecasting model and create behavioral predictions. As new data arrives it is aggregated and prepared in real-time by Kinesis Data Analytics. The results are compared to the previously generated forecast, Amazon Cloud Watch is used to store the forecast and actual value as metrics, and when actual value deviates and cloud watch alarms trigger an incident in AWS Systems Manager, Incident manager.

Monitoring streaming data

Conclusion

The key considerations, when working with AWS Streaming Services and Streaming Applications. When you need to choose a particular service or build a solution

Usage Patterns‍

Kinesis Data Stream is for collecting and storing data, and Kinesis Data Firehose is primarily for Loading and Transforming Data Streams into AWS Data Stores and Several Saas, endpoints. Kinesis Data Analytics essentially analyzes streaming data.

Throughput

Kinesis streams scale with shards and support up to 1Mb payloads, as mentioned earlier, you have a provisioning mode and an on-demand mode for scaling shard capacity. Kinesis firehose automatically scales to match the throughput of your data. The maximum streaming throughput a single Kinesis Data Analytics for SQL application can process is approximately 100 Mbps.

Latency

‍Kinesis Streams allows data delivery from producers to consumers in less than 70 milliseconds.

Ease of use and cost

‍All the streaming services on AWS are managed and serverless, including Amazon MSK serverless, this allows for ease of use by abstracting away the infrastructure management overhead and of course, considering the pricing model of each service for your unique use case.

Project Summary

PXL is an open source social network platform for content creators. It enables users to create public or private spaces for any use such as any particular task base space or any other. Furthermore, users can take advantage of social features such as building connections, posting projects that pique the interest of other users, adding team members, notifications, project participation, and more. They can also manage their profiles and conduct a global search. This social network tool offers an online version where anyone can experience this free tool. PXL’s user interface is very logical, and users can easily navigate through various elements.

Problem Statement

The client’s requirement was to build a full-fledged backend application that can easily integrate with their prebuilt front-end application, and he later asked us to integrate the backend with the front-end.

We had to design and create a social platform where users can showcase their inventions and gain exposure. One can post any software project, categorize them, invite team members, and also participate in other projects.

Additionally, to meet the need for significant content uploads, a solution had to be developed that could easily handle the upload of media files while still being affordable and effective.

We also had to create a real-time notification system that monitors all network activity such as accepting requests, declining requests, and being removed from one’s network.

Our Solution

1. With thorough testing, responsive design, and increased efficiency and performance, we concentrated on completing each task as effectively as we could.
2. Based on the client’s requirements, we used S3 bucket, RDS, EC2, and flask microservice for media files and SES for emails.
   - Amazon S3 was used for file hosting and data persistence.
   – Amazon Relational Database Service (RDS) was used for database deployment as it simplifies the creation, operation, management, and scaling of relational databases.
   – Amazon EC2 was used for code deployment because it offers a simple web service interface for scalable application deployment.
3. We sent emails using Amazon SES because it is a simple and cost-effective way to send and receive emails using your own email addresses and domains.
4. Django-graphQL was used for the backend, and Next.js was used for the front end. Django includes a built-in object-relational mapping layer (ORM) for interacting with application data from various relational databases.
   – GraphQL aims to automate backend APIs by providing type-strict query language and a single API Endpoint where you can query all information that you need and trigger mutations to send data to the backend.
   – Next.js offers the best server-side rendering and static website development solutions. We utilized the flask microservice to help with high content uploads since flask upload files give your application the flexibility and efficiency to manage file uploading and serving.
5. Using Github’s automated CI/CD pipeline we have triggers for code lookup and deployment.

Problem Statement

Most of the tech stack was deployed on azure VMs. However, they were using archaic deployment processes with a lot of manual input, coupled with poor infra planning had resulted in a high amount of downtime.
This problem was brought into sharp relief when their user base climbed tenfold. The problem was further compounded by a lack of health checks and resource monitoring. Subpar patches to this had brought the core maintenance and enhancement operations to a screeching halt.

Our Solutions

1) The first thing that we proposed to do was to move the frontend build files to S3 in order to reduce the load on the server, post which we moved on to automating the build and deployment of docker images using git actions and terraform and setting up better resource checks by employing the built-in azure triggers.
2) Next, we proposed rewriting parts of code to better handle errors and setting up node clusters with a load balancer to help reduce the load on the primary unity servers, this also helped with reducing downtime since nodes could be safely brought down without affecting the user experience during low traffic hours.

Technologies

C#, Nodejs, AWS(SQS, S3), Azure(VM and load balancer), Unity, .Net, Docker

Success Metrics

1. Reduced down time
2. Better error alerts
3. Reduced first response time (FRT) for resource hiccups

Executive Summary

Continuing the development of a musician networking platform which involved implementing new features, enhancing the existing ones, and fixing bugs/errors/issues in the platform by improving its efficiency and productivity along with making the platform responsive.

Problem Statement

Our client wanted us to design and create a social platform where each and every user is able to connect and interact with one another easily. He came to us after a bad experience with some other company and was expecting to continue the development by improving website performance as well as efficiency.
The platform had various bugs which needed to be fixed and some major features were to be added like payment service, OTP service, adding more security along with improving existing features. Performance of platform was being affected as there were some major issues like:
1. Deployment architecture- Everything was deployed on a single EC2 instance due to which there was a high amount of downtime. The performance was impacted more when the user base was increased.
2. The videos on his platform were taking a lot of time to load.

Our Solutions

1) We followed MVC architecture for developing REST API using express as middleware and mongoose for managing data in MongoDB. Authenticated API with jwt by using JSON web token package.
2) Added payment service in the platform by integrating stripe payment gateway with help of stripe package, created OTPs for security/validation which was communicated via SMS with help of Twilio.
3) To improve the performance, we deployed the backend on a separate ec2 instance with Nginx as reverse proxy and pm2 as process manager which comes with a built-in load balancer and helps to keep the application alive forever.
4) Installed Nginx on the server, and changed the Nginx.conf file configurations as per the requirement and it worked as a load balancing solution. Also replaced the lets encrypt SSL certificates with ACM(AWS Certificate Manager) to make certificate renewal, provision, and management process better as well as easy.
5) For adding new features to the platform, the frontend involved creating several components, services, directives, pipes, and modules in Angular.
6) To reduce the load time we implemented Lazy loading with help of Lazy load routes. The reason behind increased load time for videos was the use of video tag over secured protocol, to solve this we used iframe for rendering videos which proved to be much faster.
7) Changed the existing deployment architecture and moved the front-end to S3 so that load on the server can be reduced. We moved the front-end to S3 with CloudFront as CDN for speeding up the distribution of web content and improving performance.

Technologies

Angular 10, Node, Express, MongoDB, AWS S3, EC2, CloudFront

Success Metrics

1. Provided all the deliverables within the expected deadlines, improved performance as down time reduced and videos were no longer buffering for a long time.
2. Met all the expectations of the client and with positive feedback. All his meetings with directors and students were successful due to which he wanted us to implement some more new features on his platform.
3. Continuous reporting of progress to the client.
