Get the Most out of AWS S3 With these FAQs

Almost everyone who’s used Amazon Web Services has used AWS S3. In the decade since it was first released, S3 storage has become essential to thousands of companies for file storage. While using S3 in simple ways is easy, at larger scale it involves a lot of subtleties and potentially costly mistakes, especially when your data or team are scaling up.

Amazon S3 examples Amazon Simple Storage Service (Amazon S3) is an object storage service that offers scalability, data availability, security, and performance. This section demonstrates how to use the AWS SDK for Python to access Amazon S3 services.

Sadly, as with much of AWS, we often learn some of these tips the hard way, when we’ve made mistakes or wish we’d done things differently. Without further ado, here are the ten things about AWS S3 that will help you avoid costly mistakes. We’ve assembled these tips from our own experience and the collective wisdom of several engineering friends and colleagues.

Dec 02, 2020 I set up my Amazon Simple Storage Service (Amazon S3) bucket to use default encryption with a custom AWS Key Management Service (AWS KMS) key. I want an AWS Identity and Access Management (IAM) user to be able to download from and upload to the bucket. The File I/O API is the third API that you’ll find in the Amazon.S3.IO namespace. This API is useful for applications that want to treat S3 as a file system. It does this by mimicking the.NET base classes FileInfo and DirectoryInfo with the new classes S3FileInfo and S3DirectoryInfo. We Can upload file on Amazon S3 Server directly without intervention of web server by using REST API call on S3 Server. Use Case: File upload was required on mobile app without integrating SDK because integrating SDK causes app to be heavier in size and also if it goes through our web server than it would be unnecessary consumption of resources. In HTTP terms, the upload is a simple POST request to an S3 endpoint. The request contains the file, a filename (key, in S3 terms), some metadata, and and a signed policy (more about that later). The HTTP API is very straightforward (it’s not called a simple storage service for nothing). For example, it will not check that a file exists under.

How to improve S3 performance by getting log data into and out of S3 faster

Getting data into and out of AWS S3 takes time. If you’re moving data on a frequent basis, there’s a good chance you can speed it up. Cutting down time you spend uploading and downloading files can be remarkably valuable in indirect ways — for example, if your team saves 10 minutes every time you deploy a staging build, you are improving engineering productivity significantly.

S3 is highly scalable, so in principle, with a big enough pipe or enough instances, you can get arbitrarily high throughput. A good example is S3DistCp, which uses many workers and instances. But almost always you’re hit with one of two bottlenecks:

The size of the pipe between the source (typically a server on premises or EC2 instance) and S3.
The level of concurrency used for requests when uploading or downloading (including multipart uploads).

How to improve S3 latency by paying attention to regions and connectivity

The first takeaway from this is that regions and connectivity matter. Obviously, if you’re moving data within AWS via an EC2 instance or through various buckets, such as off of an EBS volume, you’re better off if your EC2 instance and S3 region correspond. More surprisingly, even when moving data within the same region, Oregon (a newer region) comes in faster than Virginia on some benchmarks.

If your servers are in a major data center but not in EC2, you might consider using DirectConnect ports to get significantly higher bandwidth (you pay per port). Alternately, you can use S3 Transfer Acceleration to get data into AWS faster simply by changing your API endpoints. You have to pay for that too, the equivalent of 1-2 months of storage cost for the transfer in either direction. For distributing content quickly to users worldwide, remember you can use BitTorrent support, CloudFront, or another CDN with S3 as its origin.

How to Improve S3 performance by using higher bandwidth networks

Secondly, instance types matter. If you’re using EC2 servers, some instance types have higher bandwidth network connectivity than others. You can see this if you sort by “Network Performance” on the excellent ec2instances.info list.

How to use concurrency to improve AWS S3 latency and performance

Thirdly, and critically if you are dealing with lots of items, concurrency matters. Each S3 operation is an API request with significant latency — tens to hundreds of milliseconds, which adds up to pretty much forever if you have millions of objects and try to work with them one at a time. So what determines your overall throughput in moving many objects is the concurrency level of the transfer: How many worker threads (connections) on one instance and how many instances are used.

Many common AWS S3 libraries (including the widely used s3cmd) do not by default make many connections at once to transfer data. Both s4cmd and AWS’ own aws-cli do make concurrent connections, and are much faster for many files or large transfers (since multipart uploads allow parallelism).

Another approach is with EMR, using Hadoop to parallelize the problem. For multipart syncs or uploads on a higher-bandwidth network, a reasonable part size is 25–50MB. It’s also possible to list objects much faster, too, if you traverse a folder hierarchy or other prefix hierarchy in parallel.

Finally, if you really have a ton of data to move in batches, just ship it.

What is AWS S3 data optimization and how to improve lifecycles up front

Okay, we might have gotten ahead of ourselves. Before you put something in AWS S3 in the first place, there are several things to think about. One of the most important is a simple question:

When and how should this object be deleted?

Remember, large data will probably expire — that is, the cost of paying Amazon to store it in its current form will become higher than the expected value it offers your business. You might re-process or aggregate data from long ago, but it’s unlikely you want raw unprocessed logs or builds or archives forever.

At the time you are saving a piece of data, it may seem like you can just decide later. Most files are put in S3 by a regular process via a server, a data pipeline, a script, or even repeated human processes — but you’ve got to think through what’s going to happen to that data over time.

My FAVORITE VIRTUAL REALITY Zombie Apocalypse Game (Arizona .... In our experience, most AWS S3 users don’t consider lifecycle up front, which means mixing files that have short lifecycles together with ones that have longer ones. By doing this you incur significant technical debt around data organization (or equivalently, monthly debt to Amazon!).

Once you know the answers, you’ll find managed lifecycles and AWS S3 object tagging are your friends. In particular, you want to delete or archive based on object tags, so it’s wise to tag your objects appropriately so that it is easier to apply lifecycle policies. It is important to mention that S3 tagging has maximum limit of 10 tags per object and 128 unicode character. (We’ll return to this in Tip 4 and Tip 5.)

You’ll also want to consider compression schemes. For large data that isn’t already compressed, you almost certainly want to — S3 bandwidth and cost constraints generally make compression worth it. (Also consider what tools will read it. EMR supports specific formats like gzip, bzip2, and LZO, so it helps to pick a compatible convention.)

When and how is AWS S3 object modified?

As with many engineering problems, prefer immutability when possible — design so objects are never modified, but only created and later deleted. However, sometimes mutability is necessary. If S3 is your sole copy of mutable log data, you should seriously
