AWS Data Lake

A data lake is a centralized repository where you can store all of your data, whether it's structured or unstructured, at any scale.

Is a Data Lake Necessary, and What are the Benefits?

Organizations that successfully develop commercial value from their data have an edge over their competitors in the marketplace. An Aberdeen study found that companies that deployed a Data Lake outperformed their peers by 9% in organic sales growth. These leaders were able to perform new forms of analytics like machine learning on new sources including log files, data from click-streams, social media, and internet-connected devices housed in the data lake. They were able to discover, and act on, chances for business growth faster by recruiting and retaining customers, increasing productivity, proactively managing devices, and making educated decisions as a result of this.

Object storage service Amazon Simple Storage Service (S3) is the best option for building a data lake because it is the largest and most efficient. In a safe environment, where data is protected by 99.999999999 percent, you may develop and scale a data lake of any size using Amazon S3. To obtain insights from your unstructured data sets, a data lake constructed on Amazon S3 may be used to run native AWS services such as big data analytics, artificial intelligence, machine learning, high-performance computing (HPC), and media data processing applications, all of which are supported by AWS. You can use Amazon FSx for Lustre to launch file systems for high-performance computing and machine learning applications, as well as to process huge media workloads directly from your data lake. You also have the option to employ your favorite analytics, artificial intelligence, machine learning, and high-performance computing (HPC) apps from the Amazon Partner Network (APN). IT managers, storage administrators, and data scientists may all benefit from Amazon S3’s extensive set of functionality, which allows them to implement access controls, manage objects at scale, and audit activities across their S3 data lakes. For household brands like Netflix, Airbnb, Sysco, Expedia, General Electric, and the Financial Industry Regulatory Authority (FINRA), Amazon S3 hosts tens of thousands of data lakes, which are used to safely grow with their demands and to find business insights on a minute-to-minute basis.

Why use Amazon S3 for a data lake?

Amazon S3 automatically produces and keeps copies of all uploaded S3 objects across different platforms, without the need for any user intervention. This ensures that your data is accessible when needed and that it is secured from failures, errors, and other risks. 

  • Designing for security

Ensure the safety of your data with a system built specifically for enterprises with high data security requirements.

  • Instantaneous scalability

No need for extensive resource acquisition periods while increasing storage capacity.

  • Durable in the event of a complete AWS Availability Zone failure

Store data in at least three different Availability Zones (AZs). Each of the Availability Zones is separated by at least a few miles, but no more than a hundred in order to maintain minimal latency.

  • AWS services for analytics, high-performance computing, artificial intelligence, machine learning, and media data processing

Run applications on your data lake with the help of AWS native services.

  • Incorporation of services from third-party vendors

The APN allows you to connect your favorite analytics systems to your S3 data lake.

  • Multiple data handling options are available.

Comprehensive freedom to work at the object level while managing at scale, configure access, provide cost efficiencies, and audit data across an S3 data lake are all features of this solution.

Using Data Lakes to Address the Difficulties of Big Data

Data lakes are being used by organizations of all sizes and across all industries to turn data from an expense that must be handled to a useful business asset. Data lakes are essential for making sense of large amounts of data at an organizational scale. Incorporating machine learning into data lakes allows for the elimination of data silos, making it easier to evaluate various datasets while maintaining data security.

AWS Chief Technology Officer Dr. Werner Vogels discusses why organizations want to establish data lakes in his essay, “How Amazon is solving big-data difficulties with data lakes.” Dr. Vogels also points out that “a major reason firms opt to create data lakes is to break down data silos.” It is intrinsically ambiguous to have various pockets of data in different places, controlled by different groups.”

Amazon S3 allows you to migrate, store, manage, and secure any structured and unstructured data at an unlimited scale, allowing you to break down data silos. Amazon S3 is a service provided by Amazon.

Your Data Lake can Benefit from Amazon Web Services

Customers of the S3 data lake have access to a wide range of AWS analytics applications, artificial intelligence and machine learning services, and high-performance file systems. This means that you may run a variety of workloads across your data lake without having to do any additional data processing or transfer data to other storage locations. You can also use your chosen third-party analytics and machine learning tools to analyze and learn from your S3 data.

AWS Lake Formation allows you to create a data lake in days instead of months.

AWS Lake Formation enables you to establish a secure data lake in days rather than months, and it is as simple as defining where data is stored and what data access and security standards are to be used. In the following step, Lake Formation gathers data from a variety of sources and transfers it to an Amazon S3 data lake. It cleans, catalogues, and classifies data using machine learning methods, and it provides the ability to specify access control settings. Users can then access a centralized catalogue of data, which contains a list of available data sets as well as the terms and conditions under which they can be accessed and used.

Run AWS analytics applications without having to move any data.

The following purpose-built analytics services can be used to analyze data stored in an S3 data lake for a variety of use cases, from querying petabyte-scale data sets to evaluating the metadata of a single item. When using an S3 data lake, these tasks can be completed without the need for time-consuming and resource-intensive extract-transform-load (ETL) processes. Your S3 data lake can also accommodate your favorite analytics platforms.

Use S3 to store your data and run AI and Machine Learning jobs on that data.

Create recommendation machines, analyze images and videos stored in S3, and discover insights from your unstructured datasets using AWS AI services such as Amazon Comprehend, Amazon Forecast, Amazon Personalize, and Amazon Rekognition. You can quickly launch AWS AI services such as Amazon Comprehend, Amazon Forecast, Amazon Personalize, and Amazon Rekognition. As an alternative, you can use Amazon Sagemaker to quickly construct, train, and deploy machine learning models using datasets stored in S3.

S3 Select allows you to query data already in place in a jiffy.

Application developers can use S3 Select to transfer the time-consuming task of filtering and accessing data contained within objects to the cloud. It is possible to query object metadata without having to move the object to another data store with S3 Select. S3 Select can enhance the performance of most applications that often request data from S3 by up to 400 percent by limiting the volume of data that must be loaded and processed by your applications. It can also lower querying expenses by up to 80 percent by doing so.

Using S3 Select in conjunction with Spark, Hive, and Presto in Amazon EMR, Amazon Athena, Amazon Redshift, and APN partners are all possible options.

Connect data to file systems in order to run high-performance applications.

In addition to providing a high-performance file system that works natively with your S3 data lake, Amazon FSx for Lustre is also optimized for the fast processing of workloads such as machine learning, high performance computing (HPC), video processing, financial modeling, and electronic design automation (EDA). A file system that delivers sub-millisecond access latency to your S3 data and allows you to read and write data at speeds of hundreds of gigabytes per second (GBps) and millions of IO per second can be set up in minutes, and you can begin using it immediately (IOPS). In the case of a file system linked to an S3 bucket, the FSx for Lustre file system transparently shows S3 objects as files and allows you to write results back into S3.

Manage your data lake more cost-effectively by utilizing S3 capabilities.

Amazon S3 is a feature-rich service that can be used to create (or re-platform) and manage a data lake of any size and for any application. It is the only cloud storage service that allows you to manage data at the object, bucket, and account levels; make changes across tens to billions of objects with a few clicks; configure granular data access policies; save money by storing objects across a variety of storage classes; and audit all activities across your S3 assets.

  • Manage data at every level throughout the whole data lake infrastructure.

Amazon S3 allows you to manage data at the object and bucket levels, as well as at the account and bucket levels. To an object, you can attach metadata tags, which you can then use to arrange data in ways that are beneficial to your company. Objects can also be organized using prefixes and buckets. Quickly point to one or a group of items to replicate across regions, restrict access, or transfer to a cheaper storage class, among other activities, using these features.

  • With a few clicks, you can take action on billions of items.

When you use S3 Batch Operations, you can perform operations on billions of objects with a single API request or a few clicks in the S3 Management Console, and you can see the status of your queries. It takes minutes instead of weeks or months to make changes to object properties and metadata and copy objects between buckets. You can also create access controls, restore archives from S3 Glacier, and run AWS Lambda functions all from within S3.

  • Set up strict controls over who has access to critical information.

Restrict access to certain buckets and objects using bucket policies, object tags, and ACLs. In order to control who has access to what parts of your AWS account, you can make use of AWS Identity and Access Management. It is possible to restrict access to a bucket of objects or an entire AWS account by configuring S3 Block Public Access to block all access requests.

  • Save money by storing data in many S3 Storage Classes.

Access requirements vary widely, and so do the costs associated with storing data in S3’s six various storage classes. Using S3 Storage Class Analysis, you may discover how your data is being used. You can then use S3 Glacier or S3 Glacier Deep Archive for optimal cost savings by configuring lifespan policies for less frequently accessed objects.

  • All S3 resource requests and other activity should be scrutinized.

Quickly find out who is requesting access to what data and from where, audit object metadata (such as retention date, business unit, and encryption status), monitor consumption and prices, study access trends, among other activities connected to your S3 resources with reporting tools. Changes can be made to your data lake and the apps that rely on it based on these insights, which can help you save money.
