Jet built its entire e-commerce platform, including development and delivery infrastructure, on Microsoft #Azure.
Jet.com - E-commerce challenger eyes the top spot, runs on the Microsoft cloud
Marc Lore is perhaps best known as the creator of the popular e-commerce site Diapers.com, which was eventually sold to Amazon. Now, the entrepreneur and his team are ready to compete head-on with the e-retailing giant through an innovative online marketplace called Jet.com. To get up and running quickly, Jet built its entire e-commerce platform, including development and delivery infrastructure, on Microsoft Azure, using both .NET and open-source technologies.
Business Challenge
In 2010, Marc Lore sold his company Quidsi (which ran e-retailing sites like Diapers.com and Soap.com) to Amazon for $550 million. Four years later, Marc is competing against Amazon directly—with the creation of a new online marketplace called Jet.com.
There are many reasons to think that Lore might just pull it off. For one, he plans to eliminate any margins from product sales. The company’s only source of revenue will come from membership dues, eliminating the kind of mark-ups that Amazon charges and passing the savings on to the customer. In addition, an innovative pricing engine will work to reduce or eliminate costs in the e-commerce value chain, especially fulfillment costs and marketplace commissions.
“Our pricing engine will continually work out the most cost-effective way to fulfill an order from merchant locations closest to the consumer,’ explains Lore, Co-Founder and CEO of Jet. “The engine will also figure out which merchants can fulfill most cheaply by putting multiple requested items into one shipment. And so we can cut probably 10 percent of a cost of a typical e-commerce transaction just by being smarter about fulfillment.”
With a value proposition like that, the company is confidently looking forward to explosive growth. “We want to be one of the leading e-commerce destinations in a very short period of time—18 to 36 months,” says Mike Hanrahan, CTO at Jet.
To fuel that growth, Jet was able to quickly secure more than $220 million in financing. Meanwhile, aggressive marketing has already created a user base of more than 400,000 customers—even before the site launched.
Next step: find the right cloud partner to support the company’s ambitious growth plan. “We realized that we simply did not have the resources to build and manage the kind of datacenters and development infrastructure to meet our growth strategy,” says Hanrahan. “So we quickly decided on a cloud model.”
Solution
The decision to work with Microsoft Azure was driven, in part, by the .NET development platform—and Visual F# in particular—which was a good fit with the microservices architecture used to build Jet. As Hanrahan explains, “The event-driven, microservices paradigm eliminated a lot of the overhead that comes with a service-oriented architecture such as Amazon uses, meaning that everyone can build all their systems in parallel and then publish and subscribe to an event bus. We found that F# works very well with this paradigm, especially the immutable data streams that are a key part of our microservices architecture.”
The Microsoft Visual Studio development system is the primary IDE for back-end infrastructure, with Node being used on the front end. To get its code through development and into production as fast as possible, Jet uses a mix of Azure App Service, Azure Web Roles and custom servers, with deployment happening from Jenkins.
Jet also has many open-source middleware components, which it runs on Azure Virtual Machines, including Elasticsearch, RedisLabs, Hadoop, and Event Store—an open-source event-sourcing data store.
Jet is taking advantage of several other Azure services to streamline its development processes. For example, to make it easier for merchant partners to integrate with the platform, it has created a developer portal for its APIs using Azure API Management.
Jet is also using Azure Key Vault to store encryption keys as well as Azure Application Insights, which will provide real-time alerts to its developers to help them identify and triage problems as they occur. Application Insights also enables Jet to learn, in real time, how customers are using their application, so they can implement an agile build-measure-learn cycle.
“Being able to leverage so many off-the-shelf services and tools from Azure enabled us to go from zero to a full- fledged e-commerce marketplace in just about 12 months. That same system would have taken us at least two years to build on our own, plus capex costs,” says Hanrahan.
The company also relies on other Microsoft cloud services to run its day-to-day business, including Office 365 and Azure Active Directory. In fact, Jet’s entire operation is now run in the cloud using Azure. “We have no servers at all onsite right now, not a single one,” says Hanrahan.
Benefits
Working with Microsoft Azure cloud services has provided Jet with a level of flexibility and scalability that has been critical to its aggressive development schedule.
Moving from code to production in minutes.
By using App Service for its consumer front end, Jet has been able to dramatically streamline its development process, so that it can build, deploy, and scale consumer-grade web apps more rapidly. As Hanrahan says, “We’ve been able to get our critical code through our CI/CD process in a couple of minutes using App Service.”
Scaling automatically to meet customer demand
As with any popular e-retailing site, Jet requires extremely rapid and flexible scaling based on ever-changing customer traffic. To streamline this process, Jet was able to set up auto-scaling on both PaaS servers and App Service to scale its servers based on load or schedule. “Because both PaaS and App Service scale automatically for us, we are able to throw as many machines as we need at the front end, when we need them,” says Hanrahan.
Accommodating rapidly growing storage requirements
As the company grows, Azure provides a wide range of storage options to handle virtually any amount of data. “Right now our data warehouse sits in a SQL Server instance, but we will be augmenting that using HD Insight,” says Hanrahan. Azure HDInsight is designed to handle any amount of data, scaling from terabytes to petabytes on demand.
With Azure, Jet has created a cloud infrastructure that’s ready to meet the company’s most ambitious growth plans. “To be one of the best e-commerce destinations in the US, we will have to handle millions of customers, placing tens of thousands of orders a day. That requires a top-class e-commerce system built on a flexible, open cloud platform. That is exactly what we got with Azure,” says Hanrahan.

Healthcare Technology Firm Launches New Perioperative Solution on Microsoft #Azure

Talis Clinical
Healthcare Technology Firm Launches New Perioperative Solution on Microsoft Azure
Talis Clinical wanted to make an innovative anesthesia information management system more widely available, so it redesigned the application to run in the cloud on Microsoft Azure. Called ACG-Anesthesia, the patient-centric solution provides centralized, automated visibility into patient risk factors and changing physiologic conditions from the decision to perform surgery through recovery.
In addition, built-in advanced clinical guidance and evidence-based care protocols empower physicians to more effectively manage all phases of perioperative care.
Making healthcare smarter
Sharing data quickly and accurately across multiple processes is important for all businesses, but nowhere is it more critical than in a hospital setting where the right information at the right time can mean the difference between life and death. Among the most critical events in patient care is the intraoperative episode, where the anesthesia care team must simultaneously monitor and react to multiple physiological parameters.
To address those challenges, an application was developed and implemented at Ohio’s Cleveland Clinic that integrates data from patient monitors, medical devices, and electronic health records (EHR) to provide centralized insight and multiparameter decision support. The anesthesia system was already being used in more than 270 operating rooms when the development team and an experienced medical entrepreneur decided to establish a new firm called Talis Clinical and offer the solution to other healthcare organizations.
Talis immediately began expanding the scope of the anesthesia system to include preoperative and postoperative events. In addition to improving patient care and safety, the extended solution would help healthcare providers get more value from the electronic health records (EHR) systems that many organizations had installed and augmented to satisfy recent regulations. Gary Colister, Chief Executive Officer of Talis, explains, “EHR technology alone does not provide the level of vigilance needed in perioperative care; it mostly enables the clinical team to record what happens.”
Moving to the cloud
Talis spent a year looking at an array of cloud platforms from specialized medical platforms to large commercial vendors. The new company decided that Microsoft Azure was the best choice for commercializing its application. “We went through all of these evaluations, and then we actually realized that we’re a Microsoft shop, with all of our technology built on a Microsoft platform,” says Colister. “We’re also moving very fast, and we needed to make sure that not only the individual pieces of software we deployed had the necessary robustness, but that our cloud partner had a deep awareness of our technology stack. It really came down to that support.”
Using the Microsoft Visual Studio development system, including Visual Studio Team Foundation Server, Talis redesigned its anesthesiology solution to run in the cloud on Microsoft Azure Virtual Machines. The highly scalable, flexible environment provides a range of benefits, including easy integration with virtually any endpoint including diverse EHRs and medical devices. On the back end, Talis gained similar advantages, including support for its databases, which ran on Linux operating systems.
The solution, called ACG-Anesthesia, continuously collects patient data such as heart rate and blood pressure, and provides real-time, clinical views of specific patient conditions in multiple rooms. It also includes electronic case summaries and hand-off checklists so that comprehensive information can be shared efficiently with all members of a medical team. ACG-Anesthesia automatically pulls data from Talis clinical products, medical devices, EHRs, lab systems, pharmacies, and more.
In the operating room, the anesthesia care team uses an intuitive touchscreen to access and record information. Elsewhere, the supervising physician can use a mobile device to remotely monitor multiple rooms staffed by nurses or other members of the care team. In addition to providing a way to monitor patient health through a central interface, the solution pushes real-time alerts to devices including tablets and smartphones. It can be customized for a wide range of scenarios, including general, cardiac, and pediatric care.
Built-in clinical guidance supports complex decisions by calculating multiple parameters and events. As a result, the solution can alert caregivers to potential adverse conditions and reactions. And besides providing operational and clinical guidance at the point of care, ACG-Anesthesia helps hospitals collect and report data required by healthcare reform acts and other regulations.
Talis is also migrating other clinical products to the cloud, including a portal that establishes and measures protocols for preoperative testing and image-based, documentation technology that is used for assessment before anesthesia is administered. Both products are already integrated with ACG-Anesthesia. Brought to market in just two years, the suite is available across North America.
Improving healthcare
By taking advantage of Microsoft Azure, Talis Clinical can help medical organizations throughout North America improve patient care and safety at all stages of treatment and recovery.
Provides better support for innovation
With the Microsoft cloud, Talis was able to launch an innovative product that can help hospitals improve performance. “We have determined that Microsoft Azure can help us serve clients better than other traditional platforms,” says Colister. “We want our clients to feel like we can deliver the highest level of service that they expect. To be able to provide insights that help clinicians be more vigilant and at the same time produce legal documentation for compliance—that’s a big achievement in our space.”
Improves patient outcome
By providing timely, relevant data through remote apps and devices, Talis can help clinicians improve patient care. “The perioperative surgical care model is being studied at a lot of prominent medical centers around the country, and it emphasizes continuity and measuring patient information from the preop to surgery, subsequent physical therapy, and beyond discharge” says Karen Alexander, Vice President of Business Intelligence at Talis Clinical. “With Microsoft Azure, we can build the technology to implement this new care model and improve patient outcomes.”
Increases clinical efficiency
Talis is also improving workflow for hospital staff, which frees up valuable time where it matters most. “We’re talking to clinicians who tell us that our product saves them an hour each day in documentation, and it also reduces downtime because it’s more accurate,” Colister says. “With Microsoft technology, we’re creating solutions that make physicians more productive so that they can take better care of patients.”

Case Study: Online travel company Serko upgrades cloud storage, sees significant boost in database speed and cuts costs by $120,000 annually

Case Study: Online travel company Serko upgrades cloud storage, sees significant boost in database speed and cuts costs by $120,000 annually
To provide the best possible travel booking experience for its customers, Serko upgraded its Microsoft Azure–hosted Serko Online software to Microsoft Azure Premium Storage. With this updated solution, Serko will potentially increase database transaction processing by 300 percent, which will help it accommodate planned business growth. The company also estimates that it will trim database costs by US$120,000 annually.
Booking flights online is incredibly easy: in just a few clicks, you have your ticket. But behind the scenes, databases perform thousands of transactions—searching through hundreds of available flights—in milliseconds. If the process takes too long, another travel site is only a click away.
Serko knows this well, so the company fine-tunes its datacenter infrastructure continuously to ensure that bookings are lightning-fast. Based in Auckland, New Zealand, Serko is one of the leading online corporate travel booking and expense management firms in the Asia-Pacific region. Since its founding in 1994, Serko has been an industry innovator, serving some of the largest corporations and agencies in the region.
Corporate travel departments subscribe to Serko Online for booking and Serko Incharge for expense management. Both are software-as-a-service (SaaS) products that organizations use to simplify the process of booking, approving, and reconciling travel expenditures.
Move to the cloud, enable growth
Serko is growing domestically and in emerging markets such as India, China, the Middle East, and Singapore. Since early 2014, the company has more than doubled its staff, and it aims to more than double its number of travel transactions in 2016.
To accomplish this aggressive goal, Serko needs to ensure that its datacenter infrastructure can handle a dramatic increase in transactions. The company currently performs about 300 million transactions a week.
To scale database processing power quickly and smoothly, Serko migrated the entire Serko Online application—database, application, and web servers—from its Auckland datacenter to Microsoft Azure in 2013. “Moving Serko Online and other assets to Azure gave us instant infrastructure scalability and eliminated acquisition and management costs,” says Philip Ball, Chief Technical Officer at Serko.
Azure is a cloud platform with compute, storage, networking, and other services for creating and hosting applications in Microsoft datacenters. “Azure had the best pricing of several options, and it was better aligned to our strategy because we use a great deal of Microsoft software,” Ball says.
Serko Online uses Microsoft SQL Server 2008 R2 as its database layer and originally used Microsoft Azure Standard Storage. However, the solution entails an enormous number of input/output operations per second (IOPS), and the company saw a moderate slowdown in the database tier after moving Serko Online to Azure. “The performance degradation was barely noticeable, but we were concerned about what would happen when our transaction load increased significantly,” Ball says.
Upgrade to premium cloud storage
Microsoft approached Serko about testing Microsoft Azure Premium Storage, which stores data on solid-state drives (versus the hard disk drives used by Azure Standard Storage) and provides up to 5,000 IOPS and 200 megabytes per second (MB/sec) throughput. Serko worked with Microsoft to test Serko Online on Azure Premium Storage and plans to deploy the storage technology in its production environment.
For Serko Online, Serko uses 150 A-Series Azure Virtual Machines as front-end web servers attached to eight DS-Series Azure Virtual Machines that act as database servers running SQL Server 2014. The company uses 10 Azure Premium Storage Disks for its production environment—two for backup, two for SQL Server system databases and temporary databases, three for user SQL Server data, and three for user SQL Server logs. Serko continues to use Azure Standard Storage for its disaster recovery environment. All servers communicate with each other over Azure Virtual Network. Serko currently has more than 50 SQL Server databases ranging from 2 gigabytes (GB) to 65 GB in size.
Improve performance by 300 percent
By moving to Azure Premium Storage, Serko was able to boost its database performance from 2,500 IOPS to 8,000 IOPS per pooled disk, a 300 percent increase. “We handle more than 300 million SQL Server transactions each week using eight SQL Server Azure Virtual Machines,” Ball says. “With Azure Premium Storage, we envisage that our current virtual machines can scale to handle more than 500 million SQL Server transactions weekly. This will reduce our overall costs, which is key as we scale globally.”
As a result of this performance boost, Serko believes that it can use the same number of SQL Server database servers to support three times the transaction volume with no performance degradation. “The more reduction in database-tier wait time, the better performance we can deliver,” says Ball. “As our business expands, our customers won’t hit slowdowns as our transaction loads increase. This is critical to our competitiveness.”
Serko plans to upgrade to Microsoft SQL Server 2014 and will use SQL Server AlwaysOn Availability Groups to improve performance further and gain high availability for disaster protection. During testing of AlwaysOn with Azure Premium Storage, Serko observed a 50 percent performance gain.
Reduce annual database costs
By using Azure Premium Storage in combination with DS-Series Azure Virtual Machines, Serko will be able to consolidate databases per each SQL Server instance, reducing its total number of SQL Server instances from eight to four. “With Premium Storage and the larger virtual machines, we’ll avoid [US]$120,000 a year on virtual machine and SQL Server licensing fees,” Ball says. “We can consolidate more customers onto fewer virtual machines and host larger databases.”
Gain flexibility and scalability
In addition to the Azure Virtual Machines used to run the Serko Online production environment, Serko uses Azure for its test, support, and customer staging environments—in total, 240 Azure Virtual Machines with more than 650 cores. In fact, everything except the company’s software development environment runs in Azure.
Serko developed and runs its Serko Mobile application using Microsoft Azure Cloud Services and uses Azure Service Bus as a message-passing layer between Serko applications and the many airlines and other partners with which it exchanges information. “We need the ability to scale our infrastructure quickly, and Azure gives us that,” Ball says. “We can deploy servers when we need them and shut them down when we’re done with them. Our goal is to get to a complete auto-deploy, auto-scale environment so we can quickly move software builds into production with no infrastructure hurdles. This will help the business grow.”
