Wow, I'm surprised it took AWS this long to (mostly) catch up to Azure, which had this feature back in 2015: https://learn.microsoft.com/en-us/rest/api/storageservices/understanding-block-blobs--append-blobs--and-page-blobs#about-append-blobs https://learn.microsoft.com/en-us/rest/api/storageservices/u... Azure supports 50,000 parts, zone-redundancy, and append blobs are supported in the normal "Hot" tier, which is their low-budget mechanical drive storage. Note that both 10K and 50K parts means that you can use a single blob to store a day's worth of logs and flush every minute (1,440 parts). Conversely, hourly blobs can support flushing every second (3,600 parts). Neither support daily blobs with per-second flushing for a whole day (86,400 parts). Typical designs involve a per-server log, per hour. So the blob path looks like: "{account}/{path}/{year}/{month}/{day}/{hour}_{servername}.txt" This seems insane, but it's not a file system! You don't need to create directories, and you're not supposed to read these using VIM, Notepad, or whatever. The typical workflow is to run a daily consolidation into an indexed columnstore format like Parquet, or send it off to Splunk, Log Analytics, or whatever...

AWS ranks features based on potential income from customers. Normally there’s a fairly big customer PFR needed to get a service team to implement a new feature.

  I always found it strange that AWS seems to have 2-3x as many products or services as Azure, but it has these bizarre feature gaps where as an Azure user I think: "Really? Now? In this year you're finally getting this?" (Conversely, Azure's low-level performance is woeful in comparison to AWS and they're still slow-walking the rollout of their vaguely equivalent networking and storage called Azure Boost.)

    I've only used azure a little bit, and mostly liked it - but I'd love to know what kinds of things you're referring to here (mostly on AWS only, so probably I don't even know what I'm missing out on).

      What Azure has that from what I've seen AWS does not: Resource Groups that actually act like folders, not just as special tags. Resources with human-readable names instead of gibberish identifiers. Cross-region and cross-subscription (equiv. to AWS account) views of all resources as the default, not as a special feature. Single pane-of-glass across all products instead of separate URLs and consoles for each thing. E.g.: a VM writing to an S3 bucket dedicated to it are "far apart" from each other in AWS consoles, but the equivalent resources are directly adjacent to each other in an Azure Resource Group when viewed in its Portal. Azure Application Insights is a genuinely good APM, and the Log Analytics workspace it uses under the hood is the consistent log collection platform across everything in Azure and even Entra ID and parts of Microsoft 365. It's not as featureful as Splunk, but the query language is up there in capability. Azure App Service has its flaws, but it's by far the most featureful serverless web app hosting platform. Etc...

        Kusto is wonderful. I'd love to be able to use outside of log analytics.

        Don’t forget, you don’t pay for a stopped vm in azure! You only pay while it is running. This makes things like dev environments much more affordable, since you won’t be paying for nights/weekends.

    Low level performance is underselling the issues. Blob storage is not infinitely scalable. That means it’s just not the same thing as s3.

> Wow, I'm surprised it took AWS this long to (mostly) catch up to Azure, which had this feature back in 2015: Microsoft had the benefit of starting later and learning from Amazon's failures and successes. S3 dates from 2006. That being said, both Microsoft and Google learned a lot, but also failed at learning different things. GCP has a lovely global network, which makes multi-region easy. But they spent way too much time on GCE and lost the early advantage they had with Google App Engine. Azure severely lacks in security (check out how many critical cross-tenant security vulnerabilities they've had in the past few years) and reliability (how many times have there been various outages due to a single DC in Texas failing; availability zones still aren't the default there).

If I need to consolidate anyway, is this really a win for this use case? I could just upload with {hour}_{minute}.txt instead of appending every minute, right?

  Consolidation is for archival cost efficiency and long-term analytics. If you don't append regularly, you can lose up to 59 minutes of data.

Microsoft did this by sacrificing other features of object storage that S3 and GS had since the beginning, primarily performance, automatic scaling, unlimited provisioning and cross-sectional (region wide) bandwidth. Azure blob storage did not have parity on those features back in 2015 and data platform applications could not be implemented on top of it as a result. Since then they fixed some of these, but there are still areas where Azure lacks scaling features that are taken for granted on AWS and GCP.

  Today I learned that there is a 5 PB soft capacity limit for Azure blob storage: https://learn.microsoft.com/en-us/azure/storage/common/scalability-targets-standard-account https://learn.microsoft.com/en-us/azure/storage/common/scala... Also, a 200 Gbps egress limit. How does that compare to S3? Mind you, at this scale the storage cost is about $15K/mo, so it would be cost effective to throw some developer time at the problem of scaling out between multiple storage accounts. Or just call support to have the soft limit cap raised…

In all fairness. Shipping unreliable features for unreliable services is a lot easier
