Mark Shuttleworth this morning announced Fan: their solution to container-to-container networking.

For handling container networking most use an overlay approach, which Mark described as, "You make a database in the cloud to track which IP address is attached to which container on each host VM. You then create tunnels between all the hosts so that everything can talk to everything. This works, kinda. It results in a mess of tunnels and much more complex routing than you would otherwise need. It also ruins performance for things like multicast and broadcast, because those are now exploding off through a myriad twisty tunnels, all looking the same."

Mark went on to describe the fan approach, "It’s called [fan] because you can picture it as a fan behind each of your existing IP addresses, with another 250 IP addresses available. Anywhere you have an IP you can make a fan, and every fan gives you 250x the IP addresses. More than that, you can run multiple fans, so each IP address could stand in front of thousands of container IP addresses. We use standard IPv4 addresses, just like overlays. What we do that’s new is allocate those addresses mathematically, with an algorithmic projection from your existing subnet / network range to the expanded range. That results in a very flat address structure – you get exactly the same number of overlay addresses for each IP address on your network, perfect for a dense container setup. Because we’re mapping addresses algorithmically, we avoid any need for a database of overlay addresses per host. We can calculate instantly, with no database lookup, the host address for any given container address. More importantly, we can route to these addresses much more simply, with a single route to the “fan” network on each host, instead of the maze of twisty network tunnels you might have seen with other overlays."

The Intel® Compute Stick now comes in more flavours, with the announcement that an Ubuntu version (Intel product number STCK1A8LFC) will be available globally via major online and retail stockists. This new Ubuntu-based version of the Intel Compute Stick is expected to be priced at around $110 USD and will go on sale next week.

The Intel Compute Stick with Ubuntu 14.04 LTS is small enough to fit in the palm of your hand and yet is powerful enough to house an Intel Atom quad-core processor. With 64-bit Ubuntu OS embedded, the Intel Compute Stick has all the performance needed for running thin client, embedded, collaboration or cloud applications. The Intel Compute Sticks makes it easy to stay productive whether in the office, a conference room, moving from desk to desk in the workplace or even in travel. Ample onboard storage means that regardless of location, your system and files are always with you.

The on-board microSD card slot provides the option of additional storage enabling you to store even more music, movie and files more quickly and easily. And you don’t need to worry about theft, either. The Intel Compute Stick has a security notch for securing to objects with a cable, ensuring that your device moves only when you want it to.

trzalica je napisao/la:Ubuntu planira vrlo skoro zamjeniti .deb pakete sa svojim Snappy paketima koji će funkcionirati na principu nekakvog sandboxa, tj. ako neki paket prilikom update-a pukne ili nešto slično bit će ga puno jednostavnije vratiti na stare postavke i neće utjecati na stabilnost samog sustava. Uglavnom, ovo bi mogao biti cool feature...

Više o tome.

Max Bunker je napisao/la:JH-IM , ti to nekako najdetaljnije pratis pa da te pitam za mišljenje : snapy i mir kada se jednom potpuno integriraju , da li ce se to i kako odraziti na ubuntu forkove ?
