If I scroll back through my photo library, it’s astonishing how few photos I have from before 2004. And in 2006 (and probably for a few years after that), I still kept every photo I had on the hard drive of my laptop computer. If I lost that laptop, those photos would be gone forever. At some point, I went through the process to back them up to an external hard drive.
And then along came the cloud. At some point, I could give my pictures to Apple or Google and not worry about backups. There was always the possibility they could have a critical disaster and lose every wedding photo I had or all the early pictures of my kids (it could still happen). But as a father who takes way too many pictures of my kids, I no longer maintain an external drive of backups because the several terabytes of photos I have are sufficiently stored and backed up in the big cloud provider I pay to handle it. The SaaS solution in a cloud backup was more than sufficient for me.
Camera Rolls and Data Centers
Likewise, it wasn’t that long ago that any meaningful internet presence required a company to have a large server room and host their own infrastructure. That meant racks and racks of computers and an enterprise internet connection to make sure customers could access those racks of computers. Most services you relied upon had to be close by physically to deal with latency and ensure the experience worked for your customers.
Logging and metrics were kept locally, as were backups. I’m sure I’m not the only one who remembers swapping out big tape drives for daily backups and storing them in large plastic bins somewhere we really hoped wouldn’t flood.
If you were using a significant piece of software, you would need to self-host that software for many reasons—but the biggest reason was that shared infrastructure wasn’t a reality yet. There was no way to share hardware and no meaningful way to share software in a multi-tenant environment.
IaaS, the Cloud, Automated Backups and SaaS
Today, the infrastructure-as-a-service (IaaS, or “Cloud”) providers are offering everything from email hosting to Kubernetes-as-a-service (KaaS), from serverless to logging. They even make sure the software that enables your edge computing is obscured from you and managed by them (backups are automatic! And included in the price! And happen without a single person touching a tape drive!). This frees us up significantly to spend time shipping code and bits instead of fiddling with wires, CPUs and drives. It’s like shipping your photos to a SaaS photo storage provider—it takes the headache and the worry away. Yet when companies move to the cloud, many maintain the “old way” of doing things because they haven’t adjusted to the new reality yet.
There is now no need to self-host your own email service. The cloud provides it, or you can use a third-party service that runs in the same cloud. Data proximity is no longer a concern, and latency won’t suffer. Similarly, there is no need to self-host your backups or even your logging service—because the cloud will provide it, and similarly, a third-party service is no longer a latency concern—that third party is probably hosted by the same cloud in the same region.
This move to the cloud and shared infrastructure has been a game changer. SaaS is the name of the winning solution. Still, there will always be some companies with compliance or security needs that want to maintain data residency, just like there will always be people with such sensitive data or important family photos that no matter how safe and reliable the cloud is, they’ll insist on self-storage for photos and backups.
The Hybrid Solution
That’s why a hybrid cloud is the future of cloud-native solutions for complex enterprise applications and data. You host the data, but the SaaS provider hosts the application. The data stays under your control, but the SaaS firm updates the application regularly. Today, a large enterprise may have five engineers just to handle a self-hosted version of a logging app. At $180,000/year per engineer (a reasonable tech salary today), that’s almost a million dollars per year to maintain a software product that the vendor will gladly maintain for you.
This is a simple shift, but it has only become a reality recently due to advances in technology, the things the cloud has enabled and the increased headache—now seemingly unnecessarily dated—of self-hosting (and then upgrading and patching) software built by a third party.
With a hybrid cloud offering, you’re always using the latest version of the software because you’re using the software hosted and updated by the SaaS provider. There is no need to self-update, scale up or down or security patch a self-hosted install. The SaaS provider handles the compute and scaling required to make the service run smoothly. And you get the best of both worlds — zero software maintenance while still keeping your data in your own hands.
