1. Start with Storage Using Amazon S3
Amazon S3 is a secure and reliable storage solution when you are dealing with massive datasets. It's highly scalable, extremely durable, and serves as a foundation for most data workflows. You can depend on it from initial data landing zones to backup archives.
2. Spin Up Power with Amazon EC2
When you need raw computing power for heavy-duty tasks, such as batch processing or running data pipelines, EC2 gives you the flexibility to choose instance types suitable for your workloads. You're in control of the compute environment, which is key for tuning performance.
3. Simplify ETL with AWS Glue
Managing extract-transform-load operations can be messy. AWS Glue resolves this with automated data discovery, code generation, and job orchestration. AWS Glue can support you if you're managing multi-source ingestion and need to clean and prepare your data for use.
4. Query at Speed with Amazon Redshift
Redshift offers the easiest and quickest way to run complex queries against large volumes of structured data. It's perfect for powering dashboards, reports, and business intelligence tools without the drag of traditional databases.
5. Tackle Big Data with Amazon EMR
If your workloads involve distributed computing using Apache Spark or Hadoop, EMR helps you deploy and manage those clusters in a fraction of the time. It is ideal for advanced data transformations and machine learning (ML) workloads, as it integrates easily with other AWS services.
6. Event-Driven Logic with AWS Lambda
Forget provisioning servers to process a few files. Lambda allows you to write lightweight, trigger-based code that responds to data events. It is an efficient serverless solution for processing files as they arrive or triggering downstream processes.
7. Streamline Real-Time Data with Amazon Kinesis
Modern data doesn't always arrive in neat batches; it streams in constantly. Kinesis helps you manage this chaos by capturing, processing, and analyzing real-time data. You can utilize it for use cases such as log monitoring, clickstream analysis, and sensor data processing.
8. Store Fast & Flexible Data with DynamoDB
DynamoDB is a fully managed, serverless database ideal for workloads where speed and uptime are paramount. It provides a NoSQL solution that works best in situations where low latency is essential, such as recommendation engines or personalized content delivery.
9. Keep Your Metadata in Check: Glue Data Catalog
The Glue Data Catalog can be considered as a metadata hub that consolidates information regarding datasets, schemas, and transformations for you. It improves discoverability and governance—two things no engineer should overlook.
10. Coordinate Workflows with AWS Step Functions
As you know, data workflows can span multiple tools, services, and dependencies. AWS Step Functions help you string those steps together into one cohesive flow, complete with retries and error handling. It's a visual way to orchestrate and manage complex processes with clarity and ease.
Best Practices for Using AWS Tools as a Data Engineer
AWS tools are powerful, but knowing what to use isn’t enough; how you use them is what drives real impact. That’s where the best practices for using AWS services come in:
• Scalability: Use services that grow with your data. Enable auto-scaling in EC2, EMR, and Lambda to handle variable workloads.
• Automation: Set up Glue jobs, Lambda triggers, and Step Functions to run tasks without manual effort.
• Security: Encrypt your data (both at rest and in transit) and adhere to least-privilege access with IAM roles.
• Cost Monitoring: Use spot instances, archive old data in S3 Glacier, and monitor costs with AWS Budgets.
• Smart Workflows: Break pipelines into smaller, reusable steps. Use Step Functions for clear orchestration.
• Track & Monitor Everything: Use CloudWatch and CloudTrail to keep an eye on performance, errors, and user actions.
• Organize Metadata: Keep your Glue Data Catalog updated and use clear naming so your data is easy to find and understand.
• Test Before You Trust: Validate your data and test your pipelines with sample loads before pushing to production.
• Document as You Go: You can easily maintain notes on your workflows, data sources, and transformations for smoother teamwork.
Wrapping Up: Why These Services Matter
Tools that enable speed, flexibility, and automation are not just desirable; they're essential. AWS offers a comprehensive toolkit that covers all stages of the data lifecycle. By staying up to date with these services, you not only improve your performance at work but also position yourself to take the lead in a data-driven, cloud-first future.
For data engineers seeking to excel in their roles, it is beneficial to become proficient in at least 10 AWS services. By serving as the foundation for scalable and effective data pipelines, these services help businesses transform unstructured data into actionable insights. Data engineers can significantly contribute to fostering innovation and informed decision-making within their companies by leveraging the potential of Amazon Web Services.
In a world where data is the new currency, data engineers act as the architects of its flow, designing pipelines, transforming datasets, and enabling intelligent decision-making. As businesses scale and real-time data becomes mission-critical, mastering the best AWS services is no longer optional; it's essential. From data ingestion to transformation, storage, and analytics, AWS for developers and data engineers offers a comprehensive suite of cloud tools that AWS provides to build modern, scalable data ecosystems.
Let’s walk through the best AWS services and practices every data engineer should have in their 2025 toolkit.

Dynamic highlighting with Slicer:
The below example shows the dynamic highlighting where I can choose the categories in the slicer to highlight for comparison with the other categories. I can easily focus on the selected categories and compare the measure values with other categories.
Solution:
First, I have created a disconnected table with the categories. This can be easily done with the following dax formula.
Added the measure in the field value section.
Added category slicer from the Selected Category table
Finally arranged them and saw the magic happen.
Conclusion:
This goes to show the hidden features of Power BI one can explore with a little bit of tinkering with a dash of DAX. This blog is a first in a series of many nifty blogs. Hope you like it and looking forward to your feedback.

This feature provides a complete picture of the data and how each data is connected.
Another use of Tableau Catalog is linear and impact analysis. This not only shows which assets will change but also who will be affected by it, which makes work easier for many and avoids wastage of time.
EXPLAIN DATA
Tableau 2019.3 is up with a new Al-driven feature called the “Explain Data”, which helps people go from the “what” of the data to the “how” of it. With explain data, we can get an explanation for each unexpected value in the data by just a single click. On selecting the desired data point, the ‘explain data’(lightbulb) icon appears.
For each value there might be a number of explanations. Each of these explanations are checked and only the most likely ones are provided as visualizations.
Now these visualizations can be used for further explorations.
TABLEAU SERVER MANAGEMENT ADD-ON
Organizations that run critical deployment of Tableau Server at a large scale, have mentioned concerns over manageability and scalability. They have been in search for tools that could organize the management process in an efficient way, which could save a lot of time. Tableau solved this problem by introducing the Tableau Server Management Add-on – a new feature designed to help organizations manage the deployment of Tableau Server. With this, they can quickly react to the changing needs of the business as well as save time by organizing the management process in the most efficient way. Tableau Server Management Add-on, which makes running the critical deployment of tableau at a large-scale server much simpler.
The server management add-on feature can help in optimising the performance of deployment by customizing which nodes process background jobs such as extract refreshes and subscriptions and isolating these workloads, to specific nodes. This makes it easier to scale deployments to the needs of their organization.
This feature has a few tools, including two for better reliability and scalability and one for content migration, all of which helps the organizations to govern their data effectively.
