Google IaaS云平台GCE正式发布

Google官方博客上，Google副总裁Ari Balogh撰文宣布GCE正式发布，进入产品阶段（Generally Available，普遍可用）的消息。

众所周知，Google云平台最初推的是PaaS层的GAE，但发展并不顺利。在Amazon的AWS渐渐形成统治地位的时候，Google方才大梦初醒，推出GCE（Google Compute Engine）在IaaS领域竞争。

那么GCE的竞争力如何呢？

除提供24×7支持，99.95%每月的SLA保障外，正式版对操作系统的支持大大增强，几乎支持所有Linux发行版，还有Docker等软件，以及FreeBSD。虚机实例降价10%，硬盘降价60%并取消I/O费。性能上引入16核的新虚机实例，硬盘I/O速度也大大提升（峰值最大700%）。

真正的技术亮点恐怕是支持热迁移和自动重启的透明维护。

期待比较靠谱的GCE与AWS之间的比较测试。

根据Google官网，GCE已经有一些明星用户，包括Snapchat。

Google Cloud Platform gives developers the flexibility to architect applications with both managed and unmanaged services that run on Google’s infrastructure. We’ve been working to improve the developer experience across our services to meet the standards our own engineers would expect here at Google.

Today, Google Compute Engine is Generally Available (GA), offering virtual machines that are performant, scalable, reliable, and offer industry-leading security features like encryption of data at rest. Compute Engine is available with 24/7 support and a 99.95% monthly SLA for your mission-critical workloads. We are also introducing several new features and lower prices for persistent disks and popular compute instances.

Expanded operating system support

During Preview, Compute Engine supported two of the most popular Linux distributions, Debian and Centos, customized with a Google-built kernel. This gave developers a familiar environment to build on, but some software that required specific kernels or loadable modules (e.g. some file systems) were not supported. Now you can run any out-of-the-box Linux distribution (including SELinux and CoreOS) as well as any kernel or software you like, including Docker, FOG, xfs and aufs. We’re also announcing support for SUSE and Red Hat Enterprise Linux (in Limited Preview) and FreeBSD.

Transparent maintenance with live migration and automatic restart

At Google, we have found that regular maintenance of hardware and software infrastructure is critical to operating with a high level of reliability, security and performance. We’re introducing transparent maintenance that combines software and data center innovations with live migration technology to perform proactive maintenance while your virtual machines keep running. You now get all the benefits of regular updates and proactive maintenance without the downtime and reboots typically required. Furthermore, in the event of a failure, we automatically restart your VMs and get them back online in minutes. We’ve already rolled out this feature to our US zones, with others to follow in the coming months.

New 16-core instances

Developers have asked for instances with even greater computational power and memory for applications that range from silicon simulation to running high-scale NoSQL databases. To serve their needs, we’re launching three new instance types in Limited Preview with up to 16 cores and 104 gigabytes of RAM. They are available in the familiar standard, high-memory and high-CPU shapes.

Faster, cheaper Persistent Disks

Building highly scalable and reliable applications starts with using the right storage. Our Persistent Disk service offers you strong, consistent performance along with much higher durability than local disks. Today we’re lowering the price of Persistent Disk by 60% per Gigabyte and dropping I/O charges so that you get a predictable, low price for your block storage device. I/O available to a volume scales linearly with size, and the largest Persistent Disk volumes have up to 700% higher peak I/O capability. You can read more about the improvements to Persistent Disk in our previous blog post.

10% Lower Prices for Standard Instances

We’re also lowering prices on our most popular standard Compute Engine instances by 10% in all regions.

Customers and partners using Compute Engine

In the past few months, customers like Snapchat, Cooladata, Mendelics, Evite and Wix have built complex systems on Compute Engine and partners like SaltStack, Wowza, Rightscale, Qubole, Red Hat, SUSE, and Scalr have joined our Cloud Platform Partner Program, with new integrations with Compute Engine.

“We find that Compute Engine scales quickly, allowing us to easily meet the flow of new sequencing requests… Compute Engine has helped us scale with our demands and has been a key component to helping our physicians diagnose and cure genetic diseases in Brazil and around the world.”

- David Schlesinger, CEO of Mendelics

"Google Cloud Platform provides the most consistent performance we’ve ever seen. Every VM, every disk, performs exactly as we expect it to and gave us the ability to build fast, low-latency applications."

- Sebastian Stadil, CEO of Scalr

We’re looking forward to this next step for Google Cloud Platform as we continue to help developers and businesses everywhere benefit from Google’s technical and operational expertise. Below is a short video that explains today’s launch in more detail.
