Architecturing and running in multiple clouds is easy, it's exactly the same as supporting multiple datacenters and that's not something new or ground breaking.

Architecturing and running in multiple clouds is easy, it's exactly the same as supporting multiple datacenters and that's not something new or ground breaking. The only challenging part is the database access. Except cassandra, there isn't anything common or free that can take writes from multiple data centers simultaneously.

Riak Enterprise supports multiple data centers. Bet365 has, or is in the process, of purchasing all of Basho's IP, and plans are to open source the Enterprise bits[1]. Not sure if Riak is considered common, and the multi DC is not yet free. http://www.computerweekly.com/news/450426130/Riak-NoSQL-snapped-up-by-bet365 http://www.computerweekly.com/news/450426130/Riak-NoSQL-snap...

  Riak was included in the non free. I always mean free as in no money, not as freedom.

    Multi data center was restricted to Riak Enterprise and required a paid contract. That's what I was referring to, as your comment was talking about data stores that supported multi-region or multi-cloud.

      Forgot to say. I am familiar with Riak. Worked at one of the competitors of the company who acquired them. I really hope that the Entreprise version will be open sourced and will be happy to add it to the list of multi cloud options. At the moment, I can't do it in good faith since it's not gonna be released any time soon, and it's impossible to procure now that the vendor is bankrupt.

You're right, but it's worse than you say. It's also legal data requirements. Many EU businesses ask that their data never leave Europe. How do you separate your product in to multiple continents and still work seamlessly. It is not easy. Sometimes it is just easier to stand up everything you have in NA in the EU, and get a new tld (like .eu). It's a mess. Multi-cloud is HARD.

  We face this also. Out of scope of this blog post but suffice to say, you're right, it's hard.

That's like saying it's easy, except the hard part which is hard. Whatever the "application" is, making it work across multiple clouds/regions will be complex, but load-balancing is usually not a big challenge today.

  Also CockroachDB supports multiple regions as a postgresql-compatible database and Apache Pulsar is next-gen Kafka with multi-region replication built-in.

  It's easy, if you have cassandra you can multi clouds, if you don't have cassandra you can't do multi clouds. There are a few commercial products that can substitute but they don't have good advertising on HN.

    What? It's never easy, but you can definitely do multi-cloud/regions without Cassandra. It's not the only database that does multi-region nor is it a good fit for every scenario.
