Businesses and enterprises of today look for microservices when they want to set up projects involving a reasonable amount of complexity and when these have to work efficiently. Microservices seem to be the answer.

Companies like Netflix, Amazon, Uber, and PayPal are enterprises that have shifted to microservices and have become market leaders in innovation. As we have observed, microservices have the power to turn companies around in terms of technology delivery and increased and leveraged business output.

Why Microservices

Why Microservices
A microservices system essentially comprises of several independent services that are loosely coupled, and all of them communicate via APIs. The individual services are developed, deployed, and maintained by individual small teams.

Microservices help businesses and enterprises deliver projects quickly. Some of the other advantages include reliability and easy maintenance.

As per the Microservices Adoption in 2020 report, approximately 77% of enterprises/businesses adopted microservices in 2020 (out of 1,500 technology professionals). Out of these, 92% were successfully using microservices.

Given the rising popularity of microservices, it is easy to figure out that microservices developers are in high demand now and that this demand is likely to stay in the coming years.

Why should you Outsource Microservices Development

Software developer job opportunities are high in countries like the United States. High competition for tech talent has resulted in considerably high staffing times for candidates. Considering the fact that you need to appoint a large team for microservices, it is a good idea to opt for outsourcing instead of wasting time onboarding a large-sized team. The outsourcing team will do whatever is required to set up a talented microservices team.

Some of the benefits that companies can enjoy by outsourcing their software development services are listed below:

  • You will have access to the most talented software engineers in the industry
  • You can pick your team from anywhere in the world on the basis of factors such as talent and costs to the company
  • You can also get your staff to learn the best qualities from the outsourced group
  • Improve the productivity and performance of your project
  • It is enjoyable to work with a flexible business partner
  • The inherent project risks are reduced
  • Product security can be boosted to higher levels
  • You can start your project at the earliest

For software development outsourcing to work best, you should first make sure it matches your business needs and fits into the project’s schedule. It is also important to study the internal skills and resources that are available currently.

Setting aside a realistic and clear budget is important. Your organization would have to keep a lot of resources handy to shift into microservices. Outsourcing software engineers for setting up microservices would help you achieve product-market fit in the least amount of time and with unmatched results.

Microservices Systems

The microservices architecture that is used to structure applications is a modified version of the Service Oriented Architecture (SOA). Microservices make the individual applications independently deployable, highly testable, and maintainable because they are organized as a collection of loosely coupled services. This is the best structure for large applications that have to be quickly deployed regardless of their complexities.

The microservices language is named "microservice architecture pattern language," and this enables their smooth operation. This language is generally used to check the compatibility of any application with microservices.

The processes or services that communicate through a network in order to make a better application can be transformed into microservices. Microservices can be implemented using various tools and systems, including software, databases, hardware, etc.

Microservices can be used to enhance the performance of a single component or multiple components. Though the microservices for components can be used simultaneously, the microservices for a specific component are run individually.

It is important for organizations to understand that the effort required to allow microservices is enormous. Microservices that can be independently deployed require many challenges to be overcome on the UI front. Each of the microservices has to be independently tested. All of them should also be tested together to ensure smooth operation. Even if a single service fails, reconfiguration becomes inevitable.

The characteristics of microservices systems include separate functional components that can be independently employed, services split according to business capabilities, decentralized open-source solutions for problems for use by any service, implementation of the microservices as a product model, and simple communication pathways having smart endpoints.

Choose the best Outsourcing Destination

Choose a destination that has a large tech talent pool and organizations that have sufficient experience in outsourcing. As an example, India has a vast talent pool and top providers have their own development centers in many nations. The same is the case with eastern European countries like Romania, Ukraine, and Poland and some Southeast Asian nations. Among the Latin American countries, you can hire professionals from Mexico, Brazil, and Argentina.

However, a large talent pool is not the only factor. Critical understanding of the specific business domain is also an important part of microservices development.

Salary Structure for Microservices Developers

You can engage microservices models using different engagement models: freelance, full-time, or contract.

The salaries paid to microservices developers vary by the location where they are from. In India, the average salary for a microservices developer is in the range of 12K USD per annum. If you hire someone from South Africa, their salary is in the range of 29K USD per annum. Hiring a microservices developer from the US would cost you anywhere between 75K USD and 103K USD per annum.

Some companies engage microservices developers on an hourly basis. On average, in the United States, a microservices developer is paid close to 46 USD per hour. The salaries and wages paid to microservices developers are lower in developing nations when compared to developed nations like the UK and the USA.

Developer rates per hour in India are around 20 USD, 25 USD in China and other eastern countries, and 36 USD to 38 USD in eastern European countries.

Cultural Compatibility

  • Cross-cultural communication is not easy and becomes more complicated in work environments. Typically, in outsourcing, teams may be divided by different cultures and starkly diverse business approaches. The languages and traditions are also vastly different. To ensure that the entire team is on the same page, a lot of extra effort has to go into the mingling. The two basic points to keep in mind to minimize culture-associated risks are:
  • Before choosing a vendor, look for an outsourcing destination that is a cultural fit for your business.

After choosing the vendor, the teams can learn more about each other’s cultures so that they can adapt faster.

Choosing an Expert Vendor

If you are planning to migrate to microservices and you are planning to outsource your microservices development, there are some criteria that are important when choosing a vendor. Successful migration happens only when the vendor has the requisite prior experience in the development of your kind of business applications. The company should have a versatile tech portfolio that includes DevOps, data, and cloud projects.

Ensure that the vendor you outsource to has completed projects using Java, JS/TypeScript, .NET, and Python. These are widely used in large-sized microservices projects. When it comes to deployment, AWS is a favourite. Therefore, it is important that your vendor has sufficient experience in managing AWS cloud services.

Serverless technologies are becoming more popular these days. This is a situation when you can rely more on cloud service providers’ offerings than on your code and configurations. This means you can hire fewer personnel and work at reduced costs.

We believe in long-term win-win relationships with our strategic partners. If you want to migrate to microservices, call us today!The vendor should have expertise in dealing with data stores. Whereas monoliths have a single large centralized data store, microservices have an independent data store for each service. Experience with Kubernetes and ETL tools for data processing should help.

Hiring a microservices developer: What should you look for

Like any other software developer, it is essential for microservices developers to be good at both technical and soft skills. Thus recruiters can use skill assessment software like Ducknowl to test their technical and soft skills during the hiring process. It is also important that they have prior experience in the field of microservices development.

How to work with a microservices team from a software outsourcing company

The brief process is as follows:

Finding A Suitable Methodology

The development model that you need for a specific project will depend on its size, the level of complexity, the timescale that you have in mind, and your budget. The most popular methodologies are Waterfall, DevOps, Scrum, Feature-Driven Development, and Kanban.

Make Project Specifications

A detailed brief helps the developers to better understand your project and allows them to plan and appropriately prepare a workflow model.

Tracking progress

Use of project management tools ensures that the microservices projects are executed efficiently. All the stakeholders involved would benefit from documented workflows and messaging threads.

QA Testing

Do not forget to test your product from beginning to end when you choose to work with software outsourcing companies. Both the parties involved have to be responsible for QA testing to mitigate the risk of any kind of error.

Team Structure for Microservices Development

Understanding the migration from monoliths to microservices in detail is essential for building the teams that will help you in the exercise.

During the first stage of decomposition, the existing infrastructure is separated into modules or parts and checked for code duplication. This makes for a stable code which is compact and is easier to support. The second stage is decoupling, when you sever existing connections and turn the modules into separate and independently functioning microservices. This makes it easy to manage the different parts of the application. In place of a large application, developers are better off with a service that has a very narrow function to accomplish in the whole business process.

Team construction for Microservices Development

When hiring a microservices team, ensure that it is composed of the following personnel:

Software Architect

This person is responsible for designing the microservices application and executing the decomposition and decoupling processes. In addition to understanding the specific needs of the business domain, they should be able to match specific microservices to the different processes in the company.

The software architect is responsible for selecting suitable technologies for event store, service discovery, service registry, containers for various services, and implementation. They also choose appropriate integration techniques, including API gateways for the service registry, orchestration, throttling, etc.

A product team for a Microservice

This team consists of a product owner, product managers, and business analysts who turn the business requirements into technical specifications. They communicate these business needs to the development teams and also manage budgets according to current requirements.

Development team for a Microservice

For successful implementation, there should be only one development team for the end-to-end development of one microservice. At worst, this team can work on two microservices. The team size should be between 5 and 9 people, and they should work autonomously and independently. The smaller the service, the better the outcome in terms of testability, maintainability, and ability to be deployed easily. For organizations following agile methodologies, team composition would also have a Scrum master, QA engineers, and developers.

Infrastructure Team

For a small-sized project, one DevOps expert is enough. However, for a mid-sized one, you may need two such experts. They will be capable of handling CI/CD and managing environment costs.
