  1. EC2
  2. Lambda
  3. S3
  4. DynamoDB
  5. IAM
  6. Amazon Cognito
  7. Device Farm
  8. Mobile analytics
  9. SNS

1. AWS EC2 Instance

  • EC2: Amazon Elastic Compute Cloud (EC2) provides secure, scalable, on-demand hardware virtualization in the cloud.
  • Using Amazon EC2 eliminates the need to invest in server hardware upfront so that users can focus on, develop, and deploy applications faster. 
  • EC2 instances come in various hardware configurations and include an operating system.

2. Lambda Function in AWS

  • AWS Lambda lets users run snippets of code without provisioning infrastructure. 
  • This service is billed on a pay-as-you-go model, with users only paying for the execution time of their lambda code. 
  • There is no charge when the code is not running. Lambda code can be set up to automatically trigger from other AWS services or called directly from any web or mobile app.

3. Aws S3 Console

Amazon Simple Storage Service is a secure, durable, and scalable cloud-based object-store. Using this service, you can store your files in the cloud.

4. DynamoDB

Amazon DynamoDB is a high-performance, scalable cloud-based NoSQL database service.

5. Aws IAM Role

Amazon Identity and Access Management (IAM) lets you securely control who can access your AWS resources, what resources they can access, and what they can do with these resources.

6. Amazon Cognito Review

  • Amazon Cognito allows you to create identity profiles for your app's users and allows them to sign in to the app with their Amazon, Facebook, Twitter, or Google accounts.
  • After users have authenticated from the app, the app is given a token that can be used to access AWS cloud resources securely. 
  • Amazon Cognito also offers a service that allows authenticated users to sync their app data on different devices.

7. Aws Device Farm

  • Amazon Device Farm is an app testing service that allows you to upload your app and run a set of automated tests and a set of real-time tests on physical devices hosted by Amazon.
  • Both Android and iOS apps are supported.

8. Aws Mobile Analytics

  • Amazon Mobile Analytics allows you to collect and visualize app usage data. A set of reports is generated based on the collected data. 
  • You can export the analytics data to other AWS cloud services for further processing.

9. Aws SNS topic

  • Amazon Simple Notification Service (SNS) enables you to send push messages.
  • These messages can be pushed to mobile applications, e-mail inboxes, web servers, and other AWS cloud services.
  • SNS supports various protocols including SMS, e-mail, and HTTP/S.

SQL Query: 3 Methods for Calculating Cumulative SUM

-
Image
SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than...

Image
 Here are five popular SQL queries frequently used in data analysis. 1. SELECT with Aggregations Summarize data by calculating aggregates like counts, sums, averages, etc. SELECT department, COUNT(*) as employee_count, AVG(salary) as average_salary FROM employees GROUP BY department; 2. JOIN Operations  Combine data from multiple tables based on a related column. SELECT e.employee_id, e.name, d.department_name FROM employees e JOIN departments d ON e.department_id = d.department_id; 3. WHERE Clause for Filtering Filter records based on specified conditions. SELECT * FROM sales WHERE sale_date BETWEEN '2024-01-01' AND '2024-12-31'   AND amount > 1000; 4. ORDER BY Clause for Sorting Sort results in ascending or descending order based on one or more columns. SELECT product_name, price FROM products ORDER BY price DESC; 5. GROUP BY with HAVING Clause Group records and apply conditions to the aggregated results. SELECT department, SUM(salary) as total_salaries FROM employ...
