The ETL Tool of the Amazon Web Service

Amazon Web Services (AWS), a cloud computing platform from Amazon provides several cutting-edge services such as infrastructure as a service, platform as a service, packaged software as a service, and others. AWS also offers a wide range of tools that helps organizations avail of specialized facilities such as unlimited database storage, high computing power, and robust content delivery services. AWS can be segmented into different computing and storage silos and each can be configured to match user needs.

A very popular service of AWS is database migration. This can be carried out between data warehouses, relational databases, and NoSQL databases either from on-premises servers to the cloud or from one cloud provider to another. The most optimized and preferred tool for carrying out this activity is ETL AWS.

ETL, short for Extract, Transform, Load is a tool that helps combine multiple databases used for storing data into a centralized database or a data warehouse. The three processes of this cutting-edge tool are as follows - extracting data from a source, transforming the data into a specific format, and loading the processed data into the target repository.

Benefits of ETL AWS.

Since the ETL AWS tool is fully automated, there is no possibility of data loss during migration as the whole process is done without human intervention at any stage. There is also the angle of cost efficiencies too.

With ETL AWS, there is no need to make any changes to the source database or install and configure additional drivers and applications to migrate databases as the activity is started directly from the AWS Management Console. All changes at the source database are replicated to the target database through the Change Data Capture feature.

The source database remains fully functional at all times during ETL AWS migration and hence businesses do not have to resort to downtime. This feature is critical for large organizations as it will be very inconvenient to shut down systems for any period. 

All changes are updated continually between the source and target databases provided both are in sync.

AWS supports almost all common databases currently used by businesses and hence the ETL AWS tool supports all types of database migration. These include Homogeneous migration where the engines of the source and the target databases are similar or Heterogeneous migration where they are different.

Migration can be done with ETL AWS between on-premises databases to Amazon RDS or Amazon EC2, Aurora, and databases running on EC2 to RDS or vice versa. This also holds for data migration between SQL, text-based data, and NoSQL with DMS AWS.

Developers and data engineers working with ETL can create, operate, and track workflows with the AWS Glue Studio that can also be used to visually enrich, clean, and normalize data without writing the code.

With ETL AWS, get all the benefits of operating in the cloud.

Why Should You Use the ETL Tool with Amazon Web Service

When you are on the cloud-based platform Amazon Web Service (AWS), you get multiple services. Some of the advanced and more cutting-edge ones are packaged software as a service, platform as a service, and infrastructure as a service. AWS also offers various advantages over traditional databases like unlimited database storage, content delivery systems, and high computing power. All these can be individually categorized into silos for better configuration and estimating the costs of each service.

Apart from these aspects, AWS also helps to optimize database migration between relational databases, data warehouses, and NoSQL databases, either from an on-premises environment to the cloud or from one cloud provider to another. This database migration is best done with the AWS ETL tool.

ETL, an acronym for Extract, Transform, Load is a tool that combines several databases into a centralized data storage or a data warehouse. The process followed by the AWS ETL toolfor database migration runs as follows. The data is first extracted from the source database and then transformed into a structure that matches that of the target database. Finally, the processed and formatted data is loaded into the intended storage repository. 

There are several reasons why organizations prefer to use the AWS ETL toolfor database migration.

The tool is fully automated and at no stage in the migration process is human intervention required. This also ensures that the migration is error free without the possibility of any data loss, thereby making for a high-performing and cost-efficient process.

With the AWS ETL tool, businesses do not have to install or configure additional drivers and applications or make any changes to the source database before migration. This is because migration is started directly from the AWS Management Console. All changes made at the source database after the first run are easily replicated to the target database through the Change Data Capture feature.

Updates of all changes are made continually at pre-set intervals provided both the source and the target database are kept in sync. When migration is done with the AWS ETL toolthe source database remains fully functional at all times, doing away with the need to shut down systems during the migration. This aspect is very beneficial for large organizations as shutting down systems for brief periods upsets operating schedules.

Since AWS supports most common databasesthe AWS ETL tool is optimized to carry out different types of migration regardless of the structure of the databases. These are Homogeneous Migration where the engines, data types, and data codes of the source and the target database are similar or Heterogeneous Migration where all these parameters are different.

Migration is also possible between on-premises databases to Amazon RDS or Amazon EC2, Aurora, and databases running on EC2 to RDS or vice versa with the AWS ETL tool.

The Need For Replicating Oracle Databases

First, let’s dive into the core process of database replication and what it is all about.

Database replication is the method where data is located in multiple places so that the primary database is available and can be accessed from several remote locations. For this to be carried out optimally, data needs to be copied from one server to another for sharing across regions.

The prime goal of database replication is disaster recovery. In case there is an outage in the primary server, those in remote locations are automatically triggered and work is not hampered or data lost. When the outage is resolved, the primary server is updated with all changes and records that happened in the break period. This aspect is very important for large data-driven organizations. Moreover, placing a backup of the data close to users in remote locations increases database performance and speeds and reduces workloads.

Coming now to Oracle database replication, Oracle has been the mainstay of organizations around the world for decades as a highly optimized database management system. In Oracle database replication, access to data is ensured through multiple servers and sites. High data availability is also facilitated as the replication offers real-time data availability.

Oracle database replicationmakes sure that data is seamlessly distributed, and consolidated so that businesses can share it with vendors and partners in different locations as all the databases are always kept in sync mode. Further, by creating multiple copies of the database and synchronizing them for backups, business reporting, distributed data processing, testing, and disaster recovery are easily carried out.

There are several benefits of Oracle database replication.

The most critical one is that it enhances application availability as the replication copies data to several servers in various locations. Therefore, data from applications can be accessed easily as replication copies of the main server are available in various locations. Even if one of them faces an outage or a malware attack, other replicated databases can take up the slack instantly and data is not lost or breached.

Another benefit of Oracle database replicationis an improvement in the performance of databases as businesses can channel the data read functions to another replicated database during the replication process. This feature is a great help for DBAs and other authorized IT personnel, helping them to minimize processing cycles on the primary server and make it the main tool for “write” operations.

Finally, Oracle database replication guarantees improved network performance since minimum data access latency is available as multiple copies of the same data are maintained in various locations. For example, if users in “A” country face latency issues when accessing data in “B” country, the issue can be resolved by placing a replica of the data close to the user’s location.

Summing up, these are some of the key benefits of Oracle database replication.

Why Should You Use the ETL Tool for AWS Database Migration

Several reasons can be cited for using the ETL tool for AWS database migration. But before diving into the details, a quick look at the two components, AWS and ETL, individually.

AWS or the Amazon Web Service is a platform based in the cloud. Among its multiple high-powered functions are robust computing abilities, unlimited storage capabilities, and optimized content delivery. It is also a great facilitator of database migration from on-premises servers to the cloud, one cloud provider to another, relational databases, data warehouses, and NoSQL databases. To optimize the data migration process, the most used method is using the ETL tool for AWS.

The ETL part in the ETL tool for AWS stands for Extract, Transform, and Load. This tool is used to maximize the process of combining several data warehouses or databases into one centralized data storage repository. It is a three-stage activity. In the first, the data is extracted from the source database. Next, this extracted data is processed and formatted so that its structure matches the architecture of the intended target database. The final step is loading the formatted data into the selected database. This, in a nutshell, is the functioning of the ETL tool for AWS.

The reason why organizations prefer using the ETL tool for AWSfor database migration is that it is fully automated and does not require any human intervention by DBAs or others. This results in high data accuracy and data performance, as well as lower costs for migration.

Benefits of Using the ETL tool for AWS For Database Migration

Several benefits are there for using the ETL tool for AWSdatabase migration. Given below are the more critical ones.

The ETL tool for AWSenhances the performance of database migration including on-premises databases to Amazon RDS or Amazon EC2, and Aurora, as well as databases running on EC2 to RDS or vice versa. Migration is also possible between NoSQL databases, SQL, and text-based data.

What makes the ETL tool for AWSstand out among other tools in this niche is its simplicity and ease of use. It is not necessary to install and configure additional drivers and applications or make any modifications to the source database to carry out the process. Migration can be started directly from the AWS Management Console and once the process is completed, all changes and updates made subsequently at the source database are replicated via the Change Data Capture feature to the target database.

If the source and the target databases are continually kept in sync, the ETL tool for AWSupdates all changes at the source database to the target database at pre-determined intervals. Moreover, the tool ensures that during migration the source database is always fully functional.

These features make the ETL tool for AWSperfect for database migration.

The Importance and Reasons for Using Data Replicating Software

The process of copying data from a warehouse or a centralized database to one or multiple databases is called replication. There are two aspects here. The first is the publisher or the central database from where the data is to be replicated to other databases. The second or the target database is called the subscriber and is the point to which the replicating software moves the data from the publisher. However, regardless of whether the database is the publisher or the subscriber, users at all locations see and work with the same records. Typically, a subscriber is connected at a remote site on a file server or to a disconnected subscriber via a laptop.

The Importance of Replicating Software

There are several reasons for using replicating software

The most important reason is that organizations can insulate their data from any data breach or outage as the replicating software ensures the availability of copies and backups of entire databases, either on-premises or at remote locations. While a snapshot of the database can be kept at any location for the same purpose, the downside is that incremental data or changes made after the snapshot is taken are not included in the target database. Data replicating software, on the other hand, keep databases in sync and incorporates all changes provided the source and the target databases are always linked up.

Replicating software also helps users to have access to the latest data even if the databases are at remote locations. This feature comes in very handy for businesses when there is an outage or crash of the primary servers. If this happens, the secondary servers in other locations are automatically triggered and there is no break or disruption of work. When the issue is resolved, the process works in the reverse direction and updates the primary server with data and changes that occurred in the break period. Hence data durability and business continuity are maintained at all times.

The Reasons for Using Replicating Software

There are several reasons for using replicating software.

The right replicating software can take business efficiencies to the next level. It is possible to carry out data migration from a hybrid solution or undertake analytics of data in real-time as well as optimize the functions for which it is used. Other areas that businesses should focus on are the ease of access to the software and the costs of acquiring it. All these aspects are important reasons for using replicating software.

Another critical motive is optimizing a wide range of database functionalities including quick movement and synchronization of data between databases and data warehouses. The software also ensures real-time data integration in combination with log-based and non-invasive change data capture thereby lowering the costs of data warehousing and increasing availability and accessibility to information.

Optimize business functioning with the right data replicating software.

Optimizing Database Migration with the AWS ETL Tool

Amazon Web Service (AWS) is a cloud-based computing platform. Among the services offered by AWS is infrastructure as a service, platform as a service, and packaged software as a service. One of its primary features is enabling database migration between relational databases, data warehouses, and NoSQL databases. To maximize this activity, the most preferred and efficient method is the use of the AWS ETL tool.

Before going into the details of the AWS ETL tool, a look at the ETL process will help give a clear idea of the tool. ETL is an acronym for Extract, Transform, Load. These are three steps for moving data from several sources to a centralized database or data warehouse. The AWS ETL toolfirst extracts data from a source, transforms it into a structure that matches the architecture of the intended target, and then loads the data into the system of choice of organizations.

Why is theAWS ETL toolimportant for database migration?

There are several aspects how the AWS ETL tool optimizes the database migration process. Given here are a few of them.   

Data loss, minimum though it might be, due to human errors is quite common in manual migration of data. However, when the AWS ETL tool is used these possibilities are eliminated as the migration activity is fully automated.

Data is migrated in real-time within minutes with the AWSETL tool as against manual processes where migration of petabytes of data is very time-consuming. This is very inconvenient especially when real-time analysis is required. 

Manual migration requires human intervention at every step but not so with the AWS ETL tool since it is fully automated thereby saving on the costs of training personnel to maintain basic standards.

The AWS ETL tool ensures complete data consistency and reliability, a capability that cannot be avoided in manual migration processes.

These are some of the reasons why the AWS ETL tool is preferred by organizations for database migration.

There are severaltools for database migration but AWS Glue is the most optimized

While there are various tools for AWS, one that is the most optimized AWS ETL tool is AWS Glue. It makes data processing for analysis easy as it is a fully managed ETL platform. AWS Glue is very user-friendly and ETL can be configured and set up and running with just a few clicks on the AWS Management Console. Users have to just point the tool to where the data is stored after configuring AWS Glue.

The advantage of AWS Glue is that it discovers data automatically and stores the connected metadata in the AWS Glue Data Catalog. Once this is completed the data can be searched and queried instantly. It is also available on ETL.

Hence, if database migration is the goal, use the AWS ETL tool for the best results.

Database Migration with AWS DMS

AWS data migration is one of the most optimized processes to migrate on-premises databases to the cloud or from one cloud provider to another. The Database Migration Service of Amazon Web Service that enables AWS data migration provides options for either one-time data migration or continual data replication between the source and the target database provided both are continuously kept in sync. AWS DMS, a cloud-based platform also moves data between data warehouses, relational databases, or NoSQL databases.

The Functioning of AWS data migration

AWS data migrationcan work only when a link is established between the source and the target database to enable it to know from and to where the data is to be moved. Once this is done, an activity has to be defined that will load the data from the source to the target.

For DBAs, AWS data migrationis a big help as the entire database migration activity is automated and does not require human intervention even when the keys and the tables needed for migration are not present in the target database. Users can use the AWS SCT (AWS Schema Conversion Tool) for creating tables, indexes, views, and triggers in the target database in such cases. Additionally, AWS data migrationprovides all the benefits of the cloud like security, data usage elasticity, cost-efficiency, and improved performances.

Types of AWS data migration

There are two types of data movement between source and target databases with AWS data migration.

Homogeneous Database Migration

This type of migration is done when the engines of the source and the target databases, as well as the data types, data codes, and schema structures of the two are similar. It is a single-step process. The full database is migrated at one time after a link is created between the source and target. For successful migration here,the source database should either operate on an Amazon EC2 instance or an Amazon RDS database. Some common examples of Homogeneous Migration are Oracle to Amazon RDS for Oracle, MySQL to Amazon RDS for MySQL, MySQL to Amazon Aurora, and Microsoft SQL Server to Amazon RDS for SQL Server.

Heterogeneous Database Migration

This method of AWS data migrationis selected when the engines, data types and data codes, and schema structures of the source and the target databases are different. This is done over two stages. First, the data code and the schema structure are converted to a format that matches the architecture of the target database. The migration then follows the line of Homogeneous Migration. The source database can either be on an Amazon EC2 instance or an Amazon RDS database located on-site or off-premises.Examples of heterogeneous migration are Microsoft SQL Server to MySQL, Oracle to PostgreSQL, and Oracle to Amazon Aurora.

One of the two methods has to be selected depending on the structure of the databases.

Using the ETL Tool for Amazon Web Service Database Migration

One of the most optimized cloud-based platforms in use today is the Amazon Web Service (AWS). It offers a wide range of services including unlimited storage capacities and high computing powers, both very critical in the modern data-driven business environment. The advantage of AWS is that storage and computing are inseparate silos, helping businesses to accurately calculate the costs of running them.

However, it is the DMS (Database Migration Service) of AWS that is crucial for organizations to carry out database migration for which the AWS DMS ETL tool is most used because of its cutting-edge features.

ETL is short for Extract, Transform, Load and is used for combining several databases into a centralized storage repository or a data warehouse. The AWS DMS ETL tool has three functions for migrating databases from on-premises systems to the cloud or from one cloud provider to another. The first function is to extract data from the source, followed by transforming the data into a structure that is compatible with the data architecture of the intended target database. Finally, the formatted data is loaded into the target database.

Benefits of AWS DMS ETL

There are several benefits of the AWS DMS ETLtool which make it a preferred tool for businesses needing database migration. But what makes it stand out from other tools in this niche is that it is fully automated and database migration requires no human intervention, thereby eliminating the possibility of data loss or errors.

Some of the other benefits of AWS DMS ETLare as follows.

There is no need to install and configure additional drivers and applications or make changes to the source database while migrating data with the AWS DMS ETLtool. This is because the process is started directly from the AWS Management Console and any changes at the source database are constantly updated to the target through the Change Data Capture feature. However, this benefit is applicable only when the source and the target databases are perpetually kept in sync.

While migrating databases with AWS DMS ETL, the source databases are always fully functional. This is a big help for large data-driven businesses for whom shutting down systems, even for brief periods can upset operating schedules.

AWS DMS ETLallows database migration between common and most used databases, regardless of their structure, since the majority of them are supported by AWS. Both homogeneous migrations where database engines, schema structures, and data types and codes of the source and the target databases are the same, and heterogeneous migration where they are different can be done with this tool.

Migration is possible between on-premises databases to Amazon RDS or Amazon EC2, Aurora as well as databases running on EC2 to RDS or vice versa.

These are some of the advanced features of the AWS DMS ETL tool.
