If you're running a business, you're probably using Amazon Web Services (AWS) in some way or another. AWS is a suite of cloud-based services that allow enterprises to run their operations more efficiently and cost-effectively. One of the most popular services offered by AWS is S3, which is short for Simple Storage Service. It is a popular choice for businesses because it is cost-effective and scalable. You can use S3 to store any data, including photos, videos, documents, and more. Companies can use S3 to store data centrally and share it with employees or customers. In this blog post, we will discuss what S3 is and how it can be used by businesses to store and share data. We'll also cover some of the most important features of S3 and how to use them effectively.
What is S3?
S3 is a cloud-based storage service that offers businesses a cost-effective and efficient way to store and share data. The service is simple to use, making it a popular choice for businesses of all sizes. S3 offers a variety of features that make it an ideal storage solution for businesses, including high availability, durability, scalability, security, and cost-effectiveness.
How to Use S3 for Your Business
What is a Bucket in Amazon S3?
S3 is based on storage containers called "buckets." One must name an S3 bucket uniquely as the S3 namespace is global. You create your bucket in a particular region in AWS, and your data stays in that region, AWS S3 region is about data residency, but the name must be unique across all AWS customer accounts and all regions. No two buckets can share the same name.
Within buckets, files or "objects" are stored in a flat structure and named using a convention that includes an object key name representing a folder structure. For example, directory/subdirectory/filename.txt is an object key or S3 path that represents a folder structure, but since S3 buckets have a flat structure, the full key, including forward-slashes are part of the filename.
You can click through a bucket as though you are navigating a folder structure, so S3 buckets feel much like a typical filesystem.
The Most Important Features of S3
S3 offers many features that make it an ideal storage solution for businesses. These features include high availability, durability, scalability, security, and cost-effectiveness. It also offers six tiers of storage designed for different purposes, from frequent access to archival storage, and each tier has its unique features. In general though, S3 offers the following:
High availability: S3 is designed to ensure that data is always available when needed. Most tiers offer a 99.99% uptime guarantee, meaning businesses can be confident that their data will be accessible when needed.
High durability: S3 offers 99.999999999% or what they call "eleven 9's" durability, so you can rest easy that the odds of losing files are about as slim as winning the lottery in a given year.
Scalability: S3 is a scalable storage solution that can grow with your business. The service can add more storage capacity as needed, making it a flexible solution for businesses of all sizes.
Security: S3 is a secure storage solution, offering data encryption and access control capabilities. This ensures that only authorized users can access your data, keeping it safe from unauthorized access.
Cost-effectiveness: S3 is a cost-effective storage solution. You only pay for the storage you use, and there are no upfront costs.
How to Use S3 Effectively
S3 is a robust storage solution that offers businesses many benefits. To get the most out of the service, it's essential to use S3 effectively. Here are some tips for using S3 effectively:
Control Access to Your Bucket
Make sure you have set the correct access permissions for your use case. If your bucket hosts a website directly, it must be open to the public, but if it is an origin for CloudFront, it should be private with a CloudFront origin access identity as the principal in your bucket policy. If the bucket is being used as internal company storage, it should likewise have the appropriate restrictions in the bucket policy.
Use lifecycle management
S3 offers lifecycle management capabilities, which allow businesses to automate the process of moving data between different storage tiers. This can help optimize costs by moving data not frequently accessed to cheaper storage tiers.
S3 can create multiple data versions, allowing businesses to roll back to previous versions if necessary. This can be useful for restoring accidentally deleted data or reverting to a prior version of a file.
The Shared Responsibility Model
One important thing to be aware of as an AWS customer is that there is a division of responsibility between customers and AWS. In the Shared Responsibility Model Amazon is responsible for the security of the cloud, data centres, computer hardware, system upgrades for managed services, etc., but the client is responsible for security in the cloud. This means you must ensure that you have properly secured your cloud storage and other resources like EC2 instances, keeping credentials and SSH keys private, and appropriate user and resource policies (like bucket policies) to keep your data confidential.
While AWS has made managing permissions of S3 buckets much easier in recent years, it wouldn't hurt to contact us to help ensure all those ducks are lined up. We offer complete cloud migration services to ease the process.
