SmartOS

SmartOS: The Complete Modern Operating System

SmartOS is the only OS purpose-built for a multi-tenant cloud environment. It incorporates five powerful novel OS technologies — CPU Bursting, KVM, ZFS, DTrace and Zones— into a single operating system. SmartOS offers a unique combination of carrier-grade reliability, superior application performance, and flexible development environments.

CPU Bursting on Demand

A SmartMachine running SmartOS on the Fengqi.Asia Cloud automatically and effortlessly scales up to 400% in response to unexpected usage spikes by tapping unused compute resources in the cloud. This scaling of the virtual CPU and all related processes occurs instantly and does not require special scripting or spinning up additional instances.

The High Performance KVM Hypervisor

SmartOS uses second generation, hardware-assisted Kernel-Based Virtual Machine (KVM) virtualization to run applications under Windows and Linux, more efficiently and transparently than any other virtualization solution. KVM offers the fastest boot-times and extends DTrace introspection capabilities to Windows and Linux.

Reliable Data Storage with ZFS

SmartOS uses ZFS: the most reliable and resilient file system for enterprise and carrier applications. With storage pools, copy-on-write file system snapshots, adaptive replacement caching (ARC), and end-to-end data validation, ZFS delivers 100% data resiliency. Other clouds charge for premium storage. Fengqi.Asia Cloud offers it by default at no extra charge.

Superior Analytics with DTrace

The backbone of Fengqi.Asia Cloud Analytics, DTrace provides unique visibility into the system stack from top to bottom, allowing developers and system administrators to optimize for efficiency and pinpoint problems without taking applications out of production. A point-and-click heat map UI enables admins to click on pixels showing high latencies and drop down immediately into the responsible process.

Zones Keep You Safe

Amky CDN Cloud is the only public cloud to deploy Zones, a technology that acts as a digital "steel-wall" to ensure that tenants in our cloud cannot break out of their virtual servers and attack other occupants. Zones provide the best internal security in the cloud, bar none.

Scaling Architecture

Amky CDN Cloud technologies are currently used to allow applications to

• scale to support
• Billions of page views a month
• Handling tens of thousands of queries per second
• Growing from 0 to millions of users per day in less than 90 days

To achieve this kind of scale requires adopting straightforward scale architectures that combine multiple SmartMachines into scale architectures.
This section will review some of those architectural patterns.

Automatic CPU bursting provides vertical scale

Even the smallest Fengqi.Asia SmartMachine comes with automatic CPU bursting. When applications require additional power, they have immediate access to a deep resource pool for additional CPU. The performance boost is tremendous, and it comes exactly when it's required—not minutes later.
As you scale up the architecture that supports your application, this as required vertical scale reduces the need for over-provisioning in the web tier, thus saving you substantial expense.

Cloud Analytics

Know Everything About Your Cloud Environment

Amky CDN Cloud Analytics is a breakthrough technology that, for the first time ever, delivers sub-second latency analysis.

• Point-and-click UI instantly drops you from heat map into process causing latency
• Highlights outlying latency events that may affect users but are buried in average graphs
• Sub-second latency measurements allow identification of problems long before users notice
• Measures in real-time without slowing production environments or requiring a reboot
• Free to all Fengqi.Asia Cloud customers

A Wide Selection of Analytics Partners

Amky CDN Cloud Analytics complements our dedicated Stingray load balancer. This powerful enterprise-grade cloud appliance provides detailed analytics to identify sources of latency at the network level. Because it is dedicated to your Fengqi.Asia Cloud environment, Riverbed analytics show only your traffic rather than a portion of traffic in a public cloud.

Data Resiliency and Reliability

Enterprise-grade ZFS: The Most Reliable Data Storage

Amky CDN Cloud deploys the powerful ZFS file system to deliver carrier-grade storage and data reliability. The ZFS storage system at Amky CDN has the same design characteristics as the high-end SAN architectures trusted by enterprises everywhere to protect and preserve their most critical information. We put ZFS on top of a high performance local storage subsystem to ensure that your data is safe, consistent, and always accessible and recoverable. ZFS is a combined file system and logical volume manager designed for pooled local storage. Unlike other file systems deployed for cloud storage, ZFS' copy-on-write capability guarantees that your image will not be lost.

Key features of ZFS include data integrity verification against data corruption modes, support for high storage capacities, snapshots and copy-on-write clones, continuous integrity checking and automatic repair. ZFS is considered a true enterprise-grade file system and is regularly approved and deployed for mission critical file storage and storage management tasks by the large enterprises. Fengqi.Asia Cloud backs up ZFS with high-performance NFS storage subsystems that provide multiple redundancies for data backup and even greater assurance of data integrity and reliability.

Performance and Scale

A Cloud Designed to Run Apps Exceptionally Well

Amky CDN Cloud was designed from the ground up to deliver the best application performance and the most rapid scalability of any cloud. Premium Disk I/O and Network I/O support accelerate all applications running in the Fengqi.Asia Cloud. Our SmartOS SmartMachines extend this performance by allowing applications to instantly and automatically burst into large CPU pools at no charge.
In fact, each SmartOS SmartMachine can burst up to 400% instantly to handle large spikes in usage or traffic. Only SmartOS SmartMachines can resize upwards entire application stacks including multiple layers without rebooting or requiring down time. Benchmark studies have shown that Amky CDN SmartMachines deliver:

• Disk I/O 15x Faster than Amazon EC2
• Up to 32% faster CPU performance than AWS EC2
• Up to 73% faster Memory I/O than AWS EC2

Amky CDN Cloud also delivers applications exceptionally well on SmartMachines running Windows and Linux operating systems. Amky CDN Cloud's KVM hardware virtualization allows Windows and Linux SmartMachines to boot up in 15 seconds or less. In fact, Windows and Linux stacks running on the Fengqi.Asia Cloud outperform Windows and Linux stacks running on Amazon's EC2.

Steel-Wall Security

Container-based Virtualization

Amky CDN SmartMachines running container-based virtualization erect a "steel wall" around your applications. This wall prevents internal attacks. Previously, this security feature was only available to customers running SmartOS SmartMachines. Now, thanks to KVM hardware virtualization technology, Amky CDN Cloud customers running Linux and Windows SmartMachines can also deploy this feature.
Container-based virtualization allows cloud operators to create extremely secure partitions between tenants in the cloud. This prevents unauthorized users or intruders from accessing the kernel root or entering containers where they do not have access privileges. Amky CDN Cloud's steel wall container technology also ensures that, even if someone breaks out of their virtual machine they will not be able to execute commands or do any damage anywhere else inside the confines of the Fengqi.Asia Cloud.

Cloud Security Architecture

We integrate security into every layer of the cloud software stack to minimize risk and enhance security management.

Amky CDN SmartOS Provides a Firm Foundation

The Amky CDN Cloud uses the Amky CDN SmartOS and SmartDataCenter to deliver top-flight cloud security. Based on carrier-grade Solaris technology, Amky CDN SmartOS provides a solid, hardened foundation above the underlying hardware and operating system for real-time web applications. The Fengqi.Asia SmartOS integrates with the SmartDataCenter orchestration functionality and development environment to provide the optimal base for cloud security and data center security.

Application Virtualization Reduces Attack Surface

The virtual resources of each Amky CDN SmartMachine virtual CPU (vCPU) reside in the Amky CDN SmartOS rather than in the virtual machine itself. An inclusive virtualization architecture (i.e., virtualization of the operating system) eliminates potential vulnerabilities in the interface between the web application layer and the operating system from the outset, mitigating the risk of hyper-jacking and reducing the attack surface size.

Network Segmentation for the Cloud

Amky CDN Cloud uses dynamic VLANs to effectively segment multi-tenant cloud customers from one another at any time. In addition, customers can request multiple layers of cloud security within their own secure LAN segment, providing even greater and more flexible server security.

Runs on Amky CDN

Amky CDN Cloud supports thousands of software applications, application runtime environments, and other products. We also have a rich ecosystem of service partners.
