I wonder if I can blog about devops without first level setting on what the term means. Yes I’ll agree it’s used broadly, sometimes as a buzzword, sometimes as a catch-all phrase. Luckily I already wrote a post like that… What is devops and why is it important?.

Fear of automation
There’s a lot of automation happening in the cloud. A lot more configuration management (chef, puppet, ansible) is in use. I’ve seen some platform as a service companies (Heroku & EngineYard are examples of these) argue that you can now spend more on devs. You won’t need an operations staff. This raises the question Is automation killing old-school ops?.
NoSQL taking over…
If you look left some startup is building on Mongodb, and look right and another is building on Cassandra. It makes you wonder, Are sql databases dead.
Death of MySQL?
While we’re on the topic of relational databases, it’s been six years since Oracle’s purchase of Sun Microsystems. Some are still worried, Will Oracle kill MySQL?
Mistakes happen in the datacenter. Sometimes *big* mistakes. You’ll cringe at When fat fingers take down your database but hopefully learn a few things about what not to do!
Two years after a hurricane devastated lower manhattan we can still learn a lot. Real Disaster Recovery lessons from Sandy.
Every startup has a database. You ignore that management at your own peril. I wrote 10 ways avoid trouble database operations
Another week, another war story. Sometimes the job of an op, systems administrator or DBA is actually to say “no”. In this story the CTO was shouting, and tons of money was being lost every minute. Supposedly. So I wrote Does a devop need to practice the art of resistence?
Perspectives & mandates
Ops & devs look at the world in different ways. I argue that’s because the business asks them to do very different things. Devs are tasked with bringing change, through new code & product features. Ops are tasked with continuity, stability, uptime & performance. That often means resistance to change. So I wonder Does a four letter word divide dev & ops?
Database as a service?
You’re looking at Amazon Web Services, and wondering, should I use their RDS database service or build my own MySQL? Here are 10 use cases for RDS or MySQL.
On High availability
99.999% uptime you say? Is there a myth of five nines that we’re still struggling with?
Many custom Oracle applications could just as easily run on MySQL. But if you’re going to migrate from Oracle to MySQL, prepare to bushwack. Open source is a jungle!
What you don’t know can hurt you…
If you’re a manager or CTO, beware Beware what ops doesn’t tell you mysql.
