Amazon Web Services is the name that has completely revolutionized the computing world! How? Amazon Web Services or AWS is a cloud service provided by Amazon in which you can find different building blocks as services to develop and implement any type of cloud application. The various AWS services are designed to work in unison with each other to develop highly sophisticated and scalable applications.
Why is Data Analytics Important?
Data analytics helps companies gain more visibility and a deeper understanding of their processes and services. It gives them detailed insights into the customer experience and customer problems. By shifting the paradigm beyond data to connect insights with action, companies can create personalized customer experiences, build related digital products, optimize operations, and increase employee productivity.
How Does Big Data Analytics Work?
Big data analytics follows five steps to analyze any large datasets:
This includes identifying data sources and collecting data from them. Data collection follows ETL or ELT processes.
ETL – Extract Transform Load
In ETL, the data generated is first transformed into a standard format and then loaded into storage.
ELT – Extract Load Transform
In ELT, the data is first loaded into storage and then transformed into the required format.
Based on the complexity of data, data can be moved to storage such as cloud data warehouses or data lakes. Business intelligence tools can access it when needed.
A data warehouse is a database optimized to analyze relational data coming from transactional systems and business applications. The data structure and schema are defined in advance to optimize for fast searching and reporting. Data is cleaned, enriched, and transformed to act as the “single source of truth” that users can trust. Data examples include customer profiles and product information.
A data lake is different because it can store both structured and unstructured data without any further processing. The structure of the data or schema is not defined when data is captured; this means that you can store all of your data without careful design, which is particularly useful when the future use of the data is unknown. Data examples include social media content, IoT device data, and nonrelational data from mobile apps.
Organizations typically require both data lakes and data warehouses for data analytics. AWS Lake Formation and Amazon Redshift can take care of your data needs.
When data is in place, it has to be converted and organized to obtain accurate results from analytical queries. Different data processing options exist to do this. The choice of approach depends on the computational and analytical resources available for data processing.
All processing happens on a dedicated central server that hosts all the data.
Data is distributed and stored on different servers.
Pieces of data accumulate over time and are processed in batches.
Data is processed continually, with computational tasks finishing in seconds.
Data cleansing involves scrubbing for any errors such as duplications, inconsistencies, redundancies, or wrong formats. It’s also used to filter out any unwanted data for analytics.
This is the step in which raw data is converted to actionable insights. The following are four types of data analytics:
1. Descriptive analytics
Data scientists analyze data to understand what happened or what is happening in the data environment. It is characterized by data visualization such as pie charts, bar charts, line graphs, tables, or generated narratives.
2. Diagnostic analytics
Diagnostic analytics is a deep-dive or detailed data analytics process to understand why something happened. It is characterized by techniques such as drill-down, data discovery, data mining, and correlations. In each of these techniques, multiple data operations and transformations are used for analyzing raw data.
3. Predictive analytics
Predictive analytics uses historical data to make accurate forecasts about future trends. It is characterized by techniques such as machine learning, forecasting, pattern matching, and predictive modeling. In each of these techniques, computers are trained to reverse engineer causality connections in the data.
4. Prescriptive analytics
Prescriptive analytics takes predictive data to the next level. It not only predicts what is likely to happen but also suggests an optimum response to that outcome. It can analyze the potential implications of different choices and recommend the best course of action. It is characterized by graph analysis, simulation, complex event processing, neural networks, and recommendation engines.

Top 10 AWS Data Analytics Services
Before we start the discussion on most popular AWS platforms, it would be reasonable to go through some stats about them. It is interesting to note that AWS provides more than 70 services and the prices of the services have decreased considerably since the launch of AWS! The notable clients of AWS include Netflix, Reddit, NSA, and Expedia, which clearly show the demand for AWS.
Another noticeable factor that can be associated with the services of AWS is the addition of new features and services. Interestingly, AWS showed a 40% increase in new AWS features and services with the addition of 722 new services and features in one year. That seems to be quite a staggering growth, doesn’t it? Now, we shall move towards finding the top AWS services in demand!
The services provided by AWS are classified into several domains, and they include compute, database, messaging, migration, storage, management tools, network, and content delivery and security and identity compliance domains. However, it can be quite difficult to find out exactly which of these services are used widely.
