Slide 1: An introduction to Software as a Service (SaaS) and SaaS Hotel™ 1ST EASY WHITE PAPER | JANUARY 2010 Stephen Bell, Managing Director, 1st Easy Limited What is this document about? This document introduces company IT Management, Directors and The Board to the concept of Software as a Service (SaaS), explaining how and why software houses are adopting it as a business and supply strategy. It also introduces the SaaS Hotel™ brand from 1st Easy — its architecture and how it can help support and benefit software companies that have adopted or plan to adopt a SaaS delivery strategy. 1st Easy Limited – “Your Internet Resource Partner” www.1stEasy.com | sales@1stEasy.com | 0808 222 2221 SaaS deployment | Dedicated Servers | Colocation | Web hosting | Remote Backups | Email filtering
Slide 2: e Datacentre Colocation Business Case Contents The trend towards Software as a Service (SaaS) Key SaaS direction business drivers Key SaaS success factors SaaS Hotel™ from 1st Easy Limited The SaaS Hotel architecture Layer 1 - Enterprise-class datacentres Layer 2 – Resilient commercial grade IP transit and security Layer 3 – Network layer, local and global application management and security Layer 4 – Enterprise SAN and servers Layer 5 – Virtualisation delivery platform Layer 6 - Common Solution Service Platform (CSSP) Glossary About the author 3 3 4 6 6 7 8 Contents 10 11 12 13 14 16 2
Slide 3: e Datacentre Colocation Business Case The trend towards Software as a Service (SaaS) Your software business has traditionally sold products “in a box”, as one-off The trend towards SaaS sales. The key problem arising from this model is that as competition increases, pricing is driven down and sales counters revert to zero with each month. As a result, companies such as yours face increasing challenges to both grow and fund the continued development of applications. With the emergence of the commercial Internet, leading software vendors are adopting a “Software as a Service” (SaaS) deployment model where applications are accessed online via a web browser, as opposed to via physical formats such as boxed DVDs which are installed on the end-user’s desktop. The SaaS model introduces the idea of subscription based services, where access is rented and new features are instantly made available to users. For the vendor, this results in recurring monthly incomes from software, cost-effective worldwide deployment and a revenue platform for both growth and reinvestment into application development. Of equal importance in a competitive market, customers benefit from instant fulfilment and a better experience, including factors such as improved security, reliability and anytime-anywhere access. Key SaaS direction business drivers Need for growth of company income requires a revenue platform that is stable and increasing year on year; monthly or annual SaaS subscription incomes provide this foundation. Software development costs are increasing as application security and compliancy requirements grow; SaaS centralises application security and compliancy, reducing such costs to a minimum. 3
Slide 4: e Datacentre Colocation Business Case Need for improving global distribution of applications, best done by making applications Internet compatible. The Internet has become the distribution agent for SaaS. Need for upgrade efficiencies, not available through the software in a box distribution model, but easily possible through centralised SaaS delivery. Need to better control license security and ensure end-users adopting applications pay associated license fees. Again, SaaS ensures total centralised control of license usage. Key SaaS success factors Key SaaS success factors The success of a SaaS model extends beyond the application layer itself (quality, value, functionality, security, performance etc.) and is equally reliant on the underpinning Internet infrastructure (datacentres, networking, security, and server platforms). Such components can be graded in terms of reliability, performance and global reach: Enterprise-class datacentres with 24/7/365 technical support and high Service Level Agreements (SLAs) on power, networks and cooling. High availability, fast and reliable bandwidth (IP transit) in the required volumes. High performance servers on which applications are powered. Comprehensive physical security measures at the datacentre (24/7/365 on-site guards, access control systems, fire suppression etc.) and digital security at the network border/network application layers, to ensure applications and customer data are well protected. Remote backup datacentres with cost effective private network connections to allow the backup of vast quantities of data to a remote location, with connection speeds to restore efficiently if required. 4
Slide 5: e Datacentre Colocation Business Case Global inter-connected datacentres and relationships, in order to deploy applications closest to the end-user (minimised latency), handle Key SaaS success factors currency and customs differences and deliver the best possible experience to the end user of the applications themselves. 5
Slide 6: e Datacentre Colocation Business Case SaaS Hotel™ from 1st Easy Limited “Your apps, any place, any time” SaaS Hotel is an environment optimised for the deployment of software over the Internet. Composed of six service layers, the SaaS Hotel infrastructure has been designed to cover each aspect of successful SaaS delivery — from a reliable foundation of datacentres and networking, through to a choice of global delivery points to ensure the most responsive experience for end-users. SaaS Hotel ™ from 1st Easy Figure 1: SaaS Hotel architecture 6
Slide 7: e Datacentre Colocation Business Case Layer 1 - Enterprise-class datacentres With its roots in hosting and ecommerce application serving (the earliest deployments of SaaS monthly revenue models) and expansion into colocation services, the success of 1st Easy has been dependent on the selection of datacentres appropriate to the task. Qualifying criteria include: Physical security: 24/7/365 on-site security, access control systems, VESDA fire suppression Resilient connectivity: multiple connections with major hubs Power availability: dual UPS (Uninterruptable Power Supply) power feeds and backup generators Environmental control: resilient air conditioning By necessity, resilience is a factor taken very seriously by 1st Easy — a shortfall in any of these attributes at one of our datacentres would cost our company dearly for any outage event extending beyond just 30 minutes. SaaS benefits Vendor reputation and end-user application experience is underpinned by datacentre reliability, whilst scalable off-site backup architectures are available to protect their data. 7 SaaS Hotel architecture
Slide 8: e Datacentre Colocation Business Case Layer 2 – Resilient commercial grade IP transit and security Figure 2: Dual UK datacentre inter-connection and network configuration Highly specified datacentres, expert technical support and state of the art server architectures are important; the fact remains however, that the heaviest reliance in SaaS application delivery is the network driving it all. That's why 1st Easy have invested heavily in this area, including partacquisition of a network company. 8 SaaS Hotel architecture
Slide 9: e Datacentre Colocation Business Case Like the best, we peer directly with the best — the most important in the UK — and they reciprocate. This gets IP network packets from A to B via the most SaaS Hotel architecture direct route, enhancing end-user application performance. This strategy has proven most effective at meeting demanding Service Level Agreements (SLAs) and is capable of coping with the severest of Distributed Denial of Service (DDoS) attacks. Our dual fail-over firewall architecture has never lost the ability to deliver data packets to and from servers and further enhances security, without compromising the SLA levels. SaaS benefits Secure, high performance point-to-point delivery between your SaaS platform and end-users ensures a smooth, crisp experience, improving productivity and enhancing your credibility. 9
Slide 10: e Datacentre Colocation Business Case Layer 3 – Network layer, local and global application management and security Using network technologies from trusted suppliers such as Juniper Networks, F5 Networks, HP and Cisco, we provide protected, high availability and load balanced configurations, on both local and global scales. SaaS Hotel architecture We can add layers of additional control and security that perform the following functions: Application Local Traffic Management (LTM), optimisation and load balancing of your applications. Global Traffic Management (GTM) across multiple datacentre points of presence, ensuring constant application services, global delivery and automatic failover. Application Security Management (ASM) that significantly reduces the risk of data loss or damage and protects intellectual software property. Hardware web application acceleration, capable of improving performance by between two to ten times - reducing the need for costly hardware upgrades and improving the end user experience. SaaS benefits These advances in network technology make the deployment of SaaS far more reliable, secure, manageable and scalable to the global market. 10
Slide 11: e Datacentre Colocation Business Case Layer 4 – Enterprise SAN and servers As a direct Enterprise level customer and reseller of Dell Corporation, 1st Easy are able to source and deploy some of the most advanced and reliable server architectures available in the market today. These servers form the backbone of deployment of SaaS, delivering scalable performance, dual PSU reliability and high end configurations to support your applications. Our adoption of Dell PowerEdge® technology has introduced considerable improvements in power efficiencies, reducing by a third our server related power consumption. Quite aside from “riding the green bandwagon”, the benefits of reduced power consumption are as much about moderating datacentre operating costs as protecting the environment. As part of the strategy of virtualisation delivery (see further in this white paper), we have adopted the industry leading Storage Area Network (SAN) platform, based on EMC Corporation's CLARiiON® CX4 product range. This SAN platform delivers “five nines” (99.999%) availability, high throughput SAN storage to your applications and servers, improving uptime and application database performance. Our dual datacentre architecture allows full disaster recover procedures to be deployed, using EMC's MirrorView constant backup imaging at all data layers, without impacting on server (and hence application) performance. SaaS benefits Using the latest Enterprise server and SAN storage technologies, we can ensure SaaS operations run smoothly, cost effectively, and with the minimum of impact on the environment. 11 SaaS Hotel architecture
Slide 12: e Datacentre Colocation Business Case Layer 5 – Virtualisation delivery platform The deployment of SaaS is delivered via Virtual Private Servers (VPS). The reasons for deployment on this platform layer can be summarised as follows: VPS can be considered flexible physical hardware servers, which can be instantly deployed, moved and resized - providing the flexibility to respond to the fluid and ever changing characteristics of a SaaS environment. VPS are power efficient, utilising spare capacities of the hardware server platform layer, hence reducing the cost of SaaS deployment and providing a greener solution for the environment. Management of VPS is easier at large scales, allowing support services to easily identify servers requiring extra resources. We offer two tiers of virtualisation that are suited to different requirements and budgets: VMware at enterprise-level (comprehensive functionality) and Open Source Citrix Xen technologies at entry-level (reduced, core functionality). SaaS benefits Virtualisation improves application uptime, as resources are easily redeployed at the press of a button. It introduces greater flexibility by allowing VPS resizing on demand and helping you to grow without expensive upgrades or downtime. The result is better application platform deployment: cheaper, more reliable, and more scalable. 12 SaaS Hotel architecture
Slide 13: e Datacentre Colocation Business Case Layer 6 – Common Solution Service Platform (CSSP) Working closely with large USA-based datacentre provider CoSentry, we have extended our SaaS Hotel platform to encompass deployment in the North America. This reciprocal arrangement allows UK and European software vendors to more effectively establish North American markets, whilst USA/Canadian based vendors can expand into Europe. Forthcoming links with datacentres in Australia and Asia will provide a truly global SaaS deployment platform for the lowest latencies at end-user level. A coordinated CSSP standard provides datacentre support teams and software vendor clients with a unified platform that enables: 24/7/365 access and visibility to local support operations for clients and technicians Rapid resolution of issues Pooling of technical resources and knowledge Deployment of best technical skills to fix complex issues A single and consistent support workflow and process of resolution SaaS benefits The CSSP provides improved business continuity of applications, disaster recovery procedures and simplifies support call management on a global basis. It also provides global visibility to control local disaster situations, allowing the coordination of end-user application/data redeployment on a temporary basis, should one locality be affected by a serious outage or act of God. 13 SaaS Hotel architecture
Slide 14: e Datacentre Colocation Business Case Glossary Software as a Service (SaaS) Software deployment model where applications are accessed by users online, as opposed to locally via a program running on a desktop computer. Glossary Commercial datacentre Designed to host “mission critical” Internet applications, a purpose built commercial facility is served by resilient networks, power and environmental controls, and also offers high levels of physical and digital security. (Low) latency In the context of SaaS, latency is the perceived delay (or lag) experienced by users of online services between issuing a command and seeing a response; low latency (highly responsive performance) therefore, is desirable when delivering an application online. IP transit / bandwidth / traffic A measure of the speed or volume of traffic that is supplied to a datacentre client. Often referred to in Mbps (Megabits per second) or Gb (Gigabytes) per month. Service Level Agreement (SLA) Typically associated with a percentage figure for the guaranteed level of service over one year (e.g. 100% power SLA indicates power availability without failure during an annual period). Pre-agreed monetary compensation can often be claimed if service falls short of the stated SLA. Uninterruptable Power Supply (UPS) The provision of emergency back-up battery power to ensuring ongoing power supply to equipment in the event of a mains power failure. 14
Slide 15: e Datacentre Colocation Business Case Resilience / redundancy The provision of fault tolerant services, generally in the area of networks and power. For example, a resilient network will consist of at least two routes, so that if one fails, the second (backup) network will continue to service Internet traffic. Load balancing Intelligent distribution of traffic amongst a server cluster to optimise application performance and reliability. Glossary 15
