Cronicle - fresh install

[BenKentzer]

Hello!

I'm currently migrating a load of tech across into a new set of VPCs within AWS. We share the current ones with some other applications, and as these have all matured it's making sense to split things out. We're also facing issues with overlapping CIDR blocks now we're part of a larger organisation (I've mitigated this for now, but it's tech debt that I don't want longer term).

We use Cronicle currently, and have 4 instances in 2 VPCs in 2 regions.

I'm just trying to work out whether we should put in a brand new install of Cronicle in our new set of VPCs (alongside the existing one so we can migrate jobs one by one) or whether we should wait for xyOps to arrive.

There's no urgent need for getting the separate scheduler in place - we can continue to use the existing instance in the short term, as we're not actually reliant on VPC-based resources for most of our jobs.

Any thoughts?

Thanks

Ben

Hey Ben!

My recommendation is to keep using Cronicle for now. xyOps is indeed coming out later this year (targeting December 31, 2025), but it is a COMPLETE ground-up rewrite. All new code. 10,000 new features.

Cronicle is battle-hardened, and has been running in live production environments since 2014, so it is very "rock solid" as they say 😉

I'm not saying xyOps will be buggy (quite the contrary -- it's actually extremely stable), I'm just saying that when it comes out, you may want to run it in dev / staging environments for a while, before you replace your production Cronicle clusters with it.

So my advice is to stick to the tried-and-true battle-ready Cronicle for the short term. Then "kick the tires" of xyOps when it drops in a few months 😊

The easiest and simplest way of migrating Cronicle clusters to new servers is doing an export, a fresh install, then an import:

Note that the export/import doesn't include any job history. If you need that, you should do a storage migration instead:

Good luck!
