Not necessarily. You can have all of above with Terraform, Ansible, Puppet, Chef... etc.

Instead of a varied interface tools set, I can have one with consistent interfaces and experiences. Kubernetes is where everything is going, hence why TF and Ansible have both recently released Kubernetes related products / features. It's their last attempt at remaining relevant (which is more than likely wasted effort in the long run). They have too much baggage (existing users in another paradigm) to make a success…

Last attempt at remaining relevant - lol.

This isn’t a competition, they are tools. Ansible is widely used and will continue to be so for a long long time. Its foundations - ssh, python and yaml are also in for the long run to manage infrastructure...

Kubernetes is for orchestrating a distributed system. What I was suggesting is to (1) make a monolith and (2) make it fast, light and high-throughput. The goal of your service is to reliably serve users at scale; this is just another way of doing it, just much more esoteric. A "C++ monolith" allows me to potentially bypass a lot of this deployment stuff because it could serve lots (millions) of users from a single bo…

I run a Dockerized monolithic application in ECS, and I'll be switching to Kubernetes soon. I am 100% sold on this approach and will never go back to any deployment methods that I've used in the past (Capistrano, Ansible, Chef, Puppet, Saltstack, etc.) I use Convox [1] which makes everything extremely simple and easy to set up on any Cloud provider.

so you build your docker images all by yourself using just a dockerfile and your statically linked app based on RHEL - for all that HIPPA and PCI compliance?? Iirc the current hottest shit of this shitshow (the dockerhub-using "ecosystem") was to use ansible in you docker builds because it's oh so declaratiev.

It gets more popular mostly because it's popular.

Congratulations, you now have source code that could potentially serve 10k users on a toaster... If only you could get it onto that toaster. How are you going to start the databases it needs? How are you going to restart it when it crashes, or worse: When it still…

Curious why run it at all? The cost must be 10 times more this way. It is mostly for the fun of learning. I come from the opposite approach. I have 4 servers two digital ocean $5 and two vulr $2.50 instances. One holds the db. One server as the frontend/code. One server to do heavy work and another to server a heavy site and holds backups. For $15 I'm hosting hundreds of sites, running so many background processes. I…

Do you manage to aggregate all logs on a single place? Do you have the same environment as staging? How do you upgrade your servers? Do you have multiple teams deploying on their own components? Do you have a monitoring/metric service? How do you query the results of a Cron? Can you rollback to the correct version when you detect an error at production?

remote syslog has been a thing for how many years?! As has using a standard distribution for your app with a non-root-user for each app, easily wiped and set up every deploy (hint: that's good for security too!). Monitoring was also a solved problem and I guess Cron logs to syslog. Rollback works just like a regular deploy? (I wonder how good k8s helps you with db-schema rollbacks?)

- Its free

- Most code running on k8s hasn't hit full production load yet.

- Where it has worked well, its been managed by devs that know what they are doing.

- It something worth putting on a backed dev resume

- Apparent cost saving ('we just need 1 vm instead of 5', 'we can auto scale to infinity','we don't have yo pay for aws, we get it all on our own vms').

Wait a few months and we will see a slurry of posts that read 'why we moved away from kubernetes', 'top 5 reasons to not use kubernetes', 'How using kubernetes fucked us, in the ass', 'You dont need kubernetes', 'Why I will never work on a project that uses kubernetes', 'Hidden costs of kubernetes' and so on.

C'mmon, you know how this works. Just take the time and read the docs. They are well written (They just don't mention where k8s does not work well)

No, not just for HIPAA/PCI compliance, that's just one of the many benefits. Here's some more reasons why I love Convox, Kubernetes/ECS, Docker:

* Effortlessly achieve 100% uptime with rolling deploys

* Running a single command to spin up a new staging environment that is completely identical to production

* Easily spinning up identical infrastructure in a different AWS region (Europe, Asia, etc.)

* Easily spinning up infrastructure inside a customer's own AWS or Google Cloud account for on-premise installations

* Automatic SSL certificates for all services. Just define a domain name in your Convox configuration, and it will automatically creates a new SSL certificate in ACM and attach it to your load balancer.

* Automatic log management for all services

* Very easily being able to set up scheduled tasks with a few lines of configuration

* Being able to run some or all of my service on AWS Fargate instead of EC2 with a single command

* Ease of deploying almost any open source application in a few minutes (GitLab, Sentry, Zulip Chat, etc.)

well, I am not really interested in your convox-ads but more in your claim that it somehow makes the typical docker-workflow of running random-software from the net somehow HIPPA and PCI-compliant? That's an interesting claim, especially with your description of it as zero-effort.

No, Convox doesn't automatically make any application compliant. Convox makes it far easier to achieve HIPAA/PCI compliance by easily setting up compliant server infrastructure:

https://docsv2.convox.com/reference/hipaa-compliance

Note that dedicated instances are no longer required for HIPAA compliance [1]. Also note that the private Convox console is completely optional. You can achieve all of this with the free and open source convox/rack project: https://github.com/convox/rack

As I mentioned in my original comment, you still need to do a lot of work to set up company policies and make sure your application complies with all regulations.

You should also be aware that I'm comparing Convox with some other popular options for HIPAA-compliant hosting:

* Aptible: https://www.aptible.com (Starts at $999 per month)

* Datica: https://datica.com (I think it starts around $2,000 per month, but not 100% sure)

These companies do provide some additional security and auditing features, but I think there's no reason to spend thousands of dollars per month when Convox can get you 95% of the way in your own AWS account. PLUS: If you have any free AWS credits from a startup program, you might not need to pay any hosting bills for years.

I'm fine with standardization, as long as I set the standard. For standard 0, I propose that the only spelling for "standardization" will be with a 'z' (which is itself pronounced "zee").

American here too -- but don't think it's reasonable to demand American spelling from the rest of the Anglophone world.

I think the downvotes are missing the point. This is a key problem with standards: sometimes they standardize around something unreasonable. And tech is already riddled with all sorts of standards which are half-implemented in n different ways.

I think a better approach would be to have a specification for more robust negotiation protocols. When I see "standardisation," I already know that this means the same thing as "standardization" and furthermore that I should expect to see "colour"/"honour," organizations referred to in plural, "from today" rather than "beginning today" or "starting today," and even "jumpers" over "sweaters," "lorries" over "trucks," "biscuits" over "cookies," and more interrogative sentences in conversation. A British English speaker likely does the same process in reverse.
