Top 6 factors to consider when choosing a reliable tech partner among Big Data consulting companies

Depending on your business goals, strategy, and needs, you may factor in various aspects when choosing the right tech partner for you. Let’s review the most common ones.

1. Location and competition for talent 

Proximity to your business can facilitate easier communication, collaboration, and project management. Partnering with a company familiar with your region's legal requirements can ensure smoother implementation and adherence to data protection laws. Additionally, a local presence often implies a better understanding of the cultural and business landscape, which can lead to more tailored and effective solutions. 

You should also consider the number of specialists within the country and the competition. For example, according to Glassdoor, Germany has over 2,340 open positions for data scientists as of March 2024. In Ukraine and Romania, these numbers are around 520 and 1,200, respectively. So, if you are to fill the position, assemble the team, and start working on the Big Data project faster, it will be more cost and time-efficient to look for the vendor in a less competitive environment and countries like Poland, Ukraine, Romania, and Bulgaria. 

2. Tech stack

For Big Data projects, you need experienced professionals proficient in respective tech stack and Scala, Java, and Python coding skills. Here’s a basic tech stack the Big Data consulting firms should be experienced in to make it to your shortlist:

  • Apache Hadoop ecosystem and Apache Spark;
  • SQL/NoSQL databases;
  • Tools such as Amazon Redshift, Apache Hive, and Amazon Athena (needed for querying data);
  • Experience in maintaining old MapReduce Java code and rewriting it using Apache Spark;
  • Kubernetes constructs (used to build Big Data CI/CD pipelines);
  • Google Cloud Dataflow or Apache Kafka (needed for data streaming and processing);
  • Cloud-based tools, including Snowflake, Azure Synapse Analytics, DataProt, Google Cloud Composer, Amazon EMR, BigQuery, Azure Data Factory, and Azure Databricks;
  • Programming languages such as Scala, Python, and Java.

You also need expertise in microservices and Big Data cloud services. Given the cloud’s elasticity, you will be able to work with large volumes of data relatively easily, scale fast, and control your data quality.

For instance, Gogo, a global in-flight connectivity provider, has partnered with N-iX, a European software development company. Gogo needed to enhance its customer experience, move its data solutions to the cloud, and develop an effective data management approach. 

The N-iX team of Big Data engineers helped the enterprise complete the transition of Gogo solutions to the cloud and build a data platform that collects and aggregates data from different sources using Spark. As a result, the company improved in-flight Internet quality, fixed antenna performance issues, could predict and prevent equipment failures, and reduced the no-fault-found rate, which helped them deliver uninterrupted customer experience.

3. Strong portfolio and reviews of Big Data projects

Another sign of quality and reliable Big Data consulting companies is their vast portfolio featuring data-related projects. Prioritize those vendors that  have cooperated with companies of different sizes and domains, as they can advise on improving the project outcomes effectively.

Also, consider their clients’ reviews and testimonials. You can find those on B2B websites like Clutch and GoodFirms.

4. Experience in processing enterprise-level data sets

Data sets from SMEs and enterprises differ in their quality, quantity, and number of sources, and you should pick the tech partner with expertise and resources to deal with the substantial amount of data. Plus, they should clearly understand the business flows and processes of a company like yours to plan the project scope, set KPIs, and advise on the team composition.

5. Long-standing Big Data engineering expertise 

Big Data analytics projects involve building an ecosystem of tools to collect a vast amount of data from different sources. These cases usually require applying Data Science, Artificial Intelligence, and Machine Learning development, cloud, IoT, and data visualization. 

6. Solid cloud expertise

It’s crucial that the Big Data solution and its architecture are suitable for scaling in the cloud. Multi-cloud and cloud-agnostic architectures help companies to scale their Big Data projects more easily. They also allow you to choose the most efficient cloud offerings and optimize the costs of your Big Data project in the long run. 

Some Big Data projects require refactoring to microservices. One of our global manufacturing clients encountered scalability challenges with its warehouse management platform due to its monolithic architecture. Our Solution Architect designed a new cloud-native infrastructure on Azure Kubernetes, facilitating easy scaling and adding new SaaS services such as anomaly detection and route recommendations. This transition to microservices enables enhanced flexibility and agility in accommodating evolving business needs and future growth.
