What's a Data Migration?
Data migration is about transferring information (data) from one place to another.
Data lake
A Data Lake is an unstructured place to put data. It’s usually meant for long term storage and infrequent querying.
Reverse ETL
Reverse ETL is the process of syncing data from your data warehouse to your business tools like Salesforce and Hubspot.
Segment
Segment helps teams track their product and marketing data and send it to whichever tools it needs to go to.
Databricks
Databricks sells a data science and analytics platform built on top of an open source package called Apache Spark.
Metadata
Metadata is data about data (🤯).
Relational database
A relational database is sort of like Excel, but for developers: it’s how applications store and analyze data.
MongoDB
MongoDB is a highly popular unstructured, NoSQL document database for powering your applications.
Confluent
Apache Kafka is a framework for streaming real time data, and Confluent offers Kafka as a managed service.

Developers hate this one thing (all about code reviews)
A deep dive into why code reviews take so long, how AI tools like CodeRabbit are speeding them up, and what great teams do to ensure clean code.
Technical Debt
Technical debt is a term developers use to refer to all of the annoying thorns they need to deal with because of past decisions someone made in their codebase and architecture.
Microservices
Microservices (all hype aside) are a way of building your application as a series of small, interacting services instead of one giant bundle of code.
Heroku
Heroku was and is one of the first cloud platforms as a service (PaaS).
Gitlab
GitLab is a giant tool for literally anything you'd want to do relating to building and deploying software.
Tokenization
Tokenization is one of the ways that backends protect sensitive information, like credit cards or social security numbers.
VPN
A Virtual Private Network (VPN) lets you route your internet access through a specialized server that keeps your sensitive information private.
Snyk
Snyk helps developers make sure that the code they're writing is secure.
Okta
Okta is an enterprise-focused identity provider: they take care of managing usernames, passwords, and permissions.
