eBay aims to move 100 per cent of its ebay.com service onto OpenStack<\/p>\n<\/div>\n

OpenStack has improved leaps and bounds in the past four years but it still leaves much to be desired in terms of upgradability and manageability, according to Subbu Allamaraju, eBay\u2019s top cloud engineer.<\/p>\n

Allamaraju, who was speaking at the OpenStack Summit in Vancouver this week, said the ecommerce giant is a big believer in open source tech when it comes to building out its own internal, dev-and-test and customer-facing services.<\/p>\n

In 2012 when the company, which is a 100 per cent KVM and OVS shop, started looking at OpenStack, it decided to deploy on around 300 servers. Now the company has deployed nearly 12,000 hypervisors on 300,000 cores, including 15 virtual private clouds, in 10 availability zones.<\/p>\n

\u201cIn 2012 we had virtually no automation; in 2014 we still needed to worry about configuration drift to keep the fleet of hypervisors in sync. In 2012, there was also no monitoring,\u201d he said. \u201cWe built tools to move workloads between deployments because in the early years there was no clear upgrade path.\u201d<\/p>\n

eBay has about 20 per cent of its customer-facing website running on OpenStack, and as of the holiday season this past year processed all PayPal transactions on applications deployed on the platform. The company also hosts significant amounts of data \u2013 Allamaraju claims eBay runs one of the largest Hadoop clusters in the world at around 120 petabytes.<\/p>\n

But he said the company still faces concerns about deploying at scale, and about upgrading, adding that in 2012 eBay had to build a toolset just to migrate its workloads off the Essex release because no clear upgrade path presented itself.<\/p>\n

\u201cIn most datacentre cloud is only running in part of it, but we want to go beyond that. We\u2019re not there yet and we\u2019re working on that,\u201d he said, adding that the company\u2019s goal is to go all-in on OpenStack within the next few years. \u201cBut at meetings we\u2019re still hearing questions like \u2018does Heat scale?\u2019\u2026 these are worrying questions from the perspective of a large operator.\u201d<\/p>\n

He also said the data from recent user surveys suggest manageability and in particular upgradeability, long held to be a significant barrier to OpenStack adoption, are still huge issues.<\/p>\n

\u201cProduction deployments went up, but 89 per cent are running a core base at least 6 months old, but 55 per cent of operators are running a year-old core base, and 18 per cent are running core bases older than 12 months,\u201d he said. \u201cLots of people are coming to these summits, but the data suggests many are worried about the upgrading.\u201d<\/p>\n

\u201cThis is an example of manageability missing in action.\u00a0 How do you manage large deployments? How do you manage upgradeability?\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
