Practical lab

This isn’t an ideal chapter for a lab because it’s a chapter on theory. So, let’s introduce a common thread in our chapters: Mega Awesome Toys. Mega Awesome Toys has hired us to consult on its cloud data transformation. The chief data officer has explained that Mega Awesome Toys has factories across the globe, with lots of IoT data coming in from machinery building toys. It also has substantial financial data from sales and toy production. It is also expanding into online sales and has a growing amount of web-based data coming in large amounts. The company has settled on AWS as its cloud provider. Its websites use MongoDB, and it has several other relational databases. Its data warehouse is on a small Microsoft SQL deployment. It has several data analysts, data scientists, and data engineers who all use Python and SQL. It also has a team of software engineers. Its long-term goal is to leverage machine learning and statistics from its data into all areas of its business. It is desperate for technology leadership as it migrates off on-premises solutions.

Solution

There are several key details to take note of:

• AWS
• MongoDB
• Microsoft SQL and other relational databases
• Python and SQL for data usage
• Data scientists, analysts, and engineers
• A team of software engineers

One possible solution is as follows:

• MongoDB has a hosted cloud offering called Atlas that is 100% compatible with AWS. So, yes, there are AWS-native choices, but given there is no need to choose an AWS product here, I would suggest a best-of-breed solution.
• Relational databases are a dime a dozen, and AWS RDS is perfect. Therefore, I would suggest choosing a flavor. I recommend PostgreSQL on RDS unless global scaling is an essential requirement; then, I would look at CockroachDB or AWS Aurora. Since there isn’t much magic in relational databases, using RDS is easy in most cases.
• Given the skills, roles, and long-term goals that have been set, I would recommend the lakehouse architecture combined with a data mesh approach. Since streaming (real-time) was directly mentioned, I would shy away from having that over Kafka and instead use Databricks as a component for the data platform. For a long time, Databricks has set itself as the front-runner for machine learning, artificial intelligence, statistics, data lakes, data warehouses, and more. It is compatible with all major cloud vendors.
