    • www.gsx.com 2 Introduction If you've been working in IT anytime during the last five years, you most likely have considered moving your IT applications to the cloud—if you haven't already migrated part or all of your infrastructure. Whether it's pressure from the C-level to reduce total cost of ownership (TCO), the increasing complexity of managing virtualized environments or demand from end users to be able to access applications and data from any device they choose and from wherever they are on the network, the move to the cloud is happening and for good reason. Some IT administrators still fear that outsourcing critical messaging and collaboration applications to the cloud could put their jobs at stake, but the move is just changing the role of the administrator, allowing them to concentrate more on high-level consideration. In this white paper, we will look at the challenges involved in moving your messaging and collaboration environments to the cloud. In addition, we examine how GSX's availability monitoring and automation management products deliver business value from both a technical and business perspective. We'll cover the following: • Why move to the cloud? • The main myths when moving applications to the cloud. • The importance of the service level agreements (SLAs). • The GSX value add. • Migration is a never-ending story—how to make it smooth?
    • www.gsx.com 3 1. Why Move to the Cloud? By leveraging the cloud, you can position your IT department as a strategic services broker which can lower the bottom line substantially for the entire organization. 1- Reasons to Move to the Cloud • Cost savings: Moving to the cloud reduces capital expenditures. Complex, virtualized infrastructure requires a significant amount of expensive storage, which cloud providers already have. • Mobility and device proliferation: End users are increasingly accessing email from smart phones and tablets while on the go. The infrastructure to support these distributed environments is often complex and needs to support heterogeneous virtualization platforms which cloud service providers have the resources to do. • Simple and scalable: The ability to dynamically scale up, down or out and allocate resources as needed without much effort. • Subscription pricing: Predictable pricing models. • Reliability: Services guaranteed by strict SLAs. • Automation: Updates and migrations can be done behind the scenes and automatically. • Security: Automated backups under specific SLAs. 2- Application Performance Management Challenges While the benefits of migrating messaging and collaboration platforms to the cloud are clear, managing the performance and availability of these in public and hybrid clouds requires specific tools which cloud service providers don't always provide. Sure, cloud providers offer service levels that are guaranteed, but how do you know if you are receiving perfect service, or at least what you expected? How do you measure the users' experience? Performance issues are the most common complaint during and after migration. Monitoring application performance and end-user experience are critical to protect your environment from service interruption and data loss. Cloud service providers are most certainly monitoring their cloud environment, but they are likely using network monitoring tools which don't dig into the application itself. Furthermore, application monitoring is often considered a "nice-to-have" feature until you experience a significant service interruption, especially with mission-critical messaging and collaboration applications. Then, it immediately becomes a "must-have." In the end, reactive approaches to performance disruptions still leave workers unproductive. To avoid this, you need monitoring and analysis tools that enable you to anticipate service disruptions before they occur. No IT administrator looks forward to calls from executives complaining that they cannot receive email, and that certainly doesn't make the IT department look like a cost-saving, strategic asset to the business as a whole.
    • www.gsx.com 4 2- The Main Myths Associated with Migrating to the Cloud The cloud is everywhere, whether it's private, hybrid or public. In this new world, companies need to maintain the same visibility and control over applications as when they were hosted on-premises. The rapid growth of the cloud is also leading to the emergence of new services, new ways for services provisioning, and new interaction models between cloud service providers and the ecosystem using cloud resources. There are a lot of myths about the performance of the messaging platforms in the cloud. 1- My Cloud Provider is Promising a Perfect Level of Service I do not need to monitor my environment because my cloud provider already is. SLAs are key as they define the quality and types of services expected by both the company and the cloud provider. They are also considered a key competitive differentiator from one service provider to another based on service up-time, level of availability, etc. But, how do you actually know if you are receiving perfect service, or at least the level of service you expected? How do you measure the users' experience? Monitoring the performance of your applications is critical to protect your environment from interruption and data loss because of server resource overload. 2- My Cloud Provider is Already Using Monitoring Tools I do not need additional monitoring tools as my cloud provider uses one already and tracks the level of performance on a regular basis. Yes, they are most certainly monitoring their cloud environment, but they are likely using network monitoring tools which are NOT monitoring performance and are NOT testing the end-user experience. So, you will have network capabilities that will never give you an exact understanding of how your applications are performing on an hourly and daily basis. 3- I Did Not Monitor my Exchange Environment while It was On-Premises so Why Would I Need to Monitor It in the Cloud? Anticipating service disruptions is the key way to avoid critical issues that have to be fixed reactively which, in turn, impact your bottom line. It is just as important to monitor on-premises and cloud environments to make sure your users will never be impacted. 4- I Do Not Need to Monitor Because my Users Tell me When Something is not Working Correctly A reactive approach like this for critical messaging platforms is very risky. Do you really want your company executives to call you up complaining that they cannot receive email? It is always a tricky situation when it comes to this point as you are going to invest time and money to solve the problems—time and money that would have been saved with a proactive approach.
    • www.gsx.com 5 3- The Importance of Service Level Agreements (SLAs) Migration is always a big concern for IT departments, and even more so when it concerns upgrading your existing on-premises environment to the cloud. In order to keep productivity high, you need to make migrations entirely transparent from an end-user experience perspective. Technical key drivers for moving to the cloud include: • Lowering TCO and capital expenditure • Optimizing storage based upon need • Increasing scalability and flexibility • Improving resource management However, moving to the cloud also raises important challenges, like service outages and performance degradation. While service disruption is inevitable in the cloud as it is on- premises, it's best not to be blind when it occurs and to have solid SLA politics in place with your cloud-service provider. Basically, SLAs are intended to ensure that the provider understands what it is required to deliver, the customer knows what to expect, and both can measure actual service performance against the SLA. There are several questions you need to ask when developing the right SLA, including: • Have you defined what services are critical to your business lines? • Are you capable of measuring the quality of these services? • Are metrics in place to justify and manage the costs associated with delivering these services to your organization? Cloud SLAs are becoming increasingly complex. For instance, data can be hosted almost anywhere and is subject to different regulations, depending on the host country. Services can also be affected by activity completely beyond the provider's control. Real-time monitoring, intelligent updates and flexibility in design means SLA management is no longer about simply showing whether a service met expectations or not; it's about giving IT managers the ability to ensure that services will proactively meet the requirements of the SLA. 1- Microsoft SLA is NOT Your End User Availability or Performance Benchmark When you sign up for Exchange Online, Microsoft provides you with a set of different SLAs. How can you ensure that the service provided by Microsoft to your management team is really as good as they promise? You need to be able to provide independent figures to prove that the quality of services is up to standard. In addition, even if Microsoft is managing your Exchange servers, how can you monitor end user experience, or any bandwidth, network or infrastructure issues that might be affecting performance?
    • www.gsx.com 6 2- Improving the Quality of Services and Justifying IT Costs You should be able to have insight into what’s going on from a user perspective because, in the end, you as an IT department are responsible for getting users to adopt a new email environment. GSX Analyzer enables you to: • Get reports on user experience of the Exchange Online services - In terms of performance - In terms of availability • Compare this user experience across all your sites • Identify any bottlenecks in your organization • Detect and analyze performance problems • Justify IT costs in terms of network or Internet providers (to fix performance issues) • Demonstrate the level of services you can provide to management, a business line and Microsoft
    • www.gsx.com 7 4- The GSX Value Add GSX Solutions is the leading provider of monitoring and reporting solutions for Microsoft (SharePoint, Exchange & Exchange Online, Lync), Blackberry and IBM applications environments. GSX is a proactive and agentless solution to help migrate and manage your messaging and collaborative environments, whether it is on-premises or in the cloud. Currently, we have over 600 customers and are monitoring over 6 million mailboxes worldwide. Our success in the monitoring marketplace is thanks to several reasons: • GSX Monitor & Analyzer is an agentless solution that allows for a seamless installation which does not impact the performance of your servers. • Our monitoring dives deeper than most tools. Our focus goes beyond “server-up” and “server-down” monitoring; we focus on the performance of your environment from an end-user perspective. • Our reporting tool, GSX Analyzer, allows you to create automate reports on the size, usage and performance of your environment. • Multi-platform monitoring means we can monitor SharePoint, Exchange On- Premises, Exchange Hybrid and Exchange Online all from a single dashboard. 1- Multi-Stations Customers may have multiple sites across a country, a continent or even the world. Moving to the cloud often means you have to select one cloud datacenter, even if your offices are spread around the globe. • How do you control, anticipate and fix performance problems for users working in a distributed environment? • How do you know if the user experience of the cloud in New York is the same as for the ones in Brazil or Singapore? The only way to measure performance properly is from the user perspective, using the cloud infrastructure from multiple sites in order to anticipate, detect, diagnose and fix all the latency problems which are bound to happen. GSX provides a real-time and consolidated view of the user experience from multiple locations so you can proactively compare, trend, identify bottlenecks, manage alerts and analyze the services. With our multi-station architecture, GSX can detect if certain sites have problems as compared to others, and determine whether the problem exists with the Exchange Online itself, or is because of network latency from the ISP or internal network.
    • www.gsx.com 8 2- GSX Cloud Synthetic Transactions GSX Monitor & Analyzer allows IT administrators to perform synthetic transactions to determine service levels of an application from an end user perspective, such as opening a mailbox, creating a folder, performing a task, sending an email etc. Mail Routing Mail routing can be done from on-premises (Domino and Exchange) to Exchange online, from online to online, or from online to echo (Internet and return). GSX tests five routes to control the email’s entire path: • Online to Online: GSX creates the email the same way an Outlook client does and then checks regularly to ensure that the mail has been delivered. If it has, GSX connects to the mailbox, opens the mail and checks the header to read the exact date of delivery. • Exchange Online to echo: GSX tests the interaction time with an external mail service and measures how long it takes to send a message from an Exchange Online mailbox to another company, as well as how long it takes to receive an email from an external mailbox. • IMAP and POP: GSX sends an email from Exchange Online to an external messaging system that works with these protocols. Contrary to the echo which measures round-trip routing, here GSX measures the one-way mail routing. • SMTP: GSX can create an email from any SMTP service on the Internet to Exchange Online. It figures out the speed of external service to Exchange Online, which is the exact opposite of the previous test. • Attachments: GSX can make sure that larger emails with attachments follow the same performance measures. Open Mailbox GSX performs every step that Outlook would have to do when a user is connecting to an Exchange Online Mailbox. If any problems happen during each of these steps, GSX will report the errors in email alerts (for example: authentication problem, server connection problem, mailbox right problem, etc.). Create Folder and Task Creating a folder in an online mailbox involves multiple tasks and checks: -­‐ Connect to Exchange -­‐ Authenticate as a user -­‐ Display the name of the mailbox -­‐ Count the number of items in that inbox -­‐ Discover and count all folders -­‐ Check the number of unread items -­‐ Create the folder locally on the Outlook client -­‐ Browse all the folders of the mailbox -­‐ Check that the folder doesn't already exist -­‐ Insert the new folder in the mailbox
    • www.gsx.com 9 To create a task, GSX automatically goes through the same steps Outlook does in creating a folder. Create a Meeting The creation of a meeting implies multiple actions that are linked with the property of a meeting. GSX automatically: • Creates an appointment locally with all its characteristics • Invites attendees • Uploads an attachment • Saves the meeting in the mailbox • Sends the meeting to all recipients Create an Email As GSX always starts by opening the mailbox of the monitored user, the first steps are always the same. Then: • The mail is created inside the mailbox • The mail is either sent to another mailbox, saved as a draft or saved in a specified folder • The object in the mail can be specified • An attachment can also be uploaded Download an Attachment In order to test the time it takes for a user to be able to download an attachment, or whether it can be downloaded at all, GSX offers multiples paths. Of course, it has to start with the opening of a mailbox as usual. Then, GSX can download the attachment of a previously selected email or a newly created one. In both cases, GSX: • Opens the mailbox • Retrieves the email where the attachment had to be downloaded • Checks how many attachments there are in the email • Downloads the first one • Erases the attachment if everything went well Search for an Item As in all the scenarios, GSX first starts by opening a mailbox where the search will be performed. Then, GSX: • Performs a recursive search where it looks in every folder and child folder for a specific word • Tests the availability and the performance of the Exchange Online Fast Search • Checks if it was able to find at least one item, otherwise the search fails.
    • www.gsx.com 10 Resolve a User A resolve-user action is the ability for the mailbox to find contacts in the user’s contact folder and the global address list (GAL). When you create an email, the Outlook client can auto-complete the name and email address. If this isn't working, each email address must be entered manually. 3- Custom Scenarios Now that each of the scenarios have been described, let’s see how you can combine them to focus on true user simulation and the ability to manipulate objects with Exchange Online. Custom scenarios allow IT administrators to link various scenarios together in order to gain visibility into the performance of each step, as well as the global performance of the complete process. Custom scenarios also help measure two very important metrics and capabilities. By linking the scenarios, you can: • Create scenarios which really reflect what a user would do at a certain time of the day. • Test the ability and the performance of Exchange Online to use items and objects that it creates. 4- Analyzing Performance Problems Monitoring URLs – Why is it Valuable? Monitoring URLs allows you to compare latency between actions performed on Exchange Online by simply pinging the Exchange Online Portal. On top of that, you can also monitor an intranet page to measure your own network latency. The URLs that GSX can monitor include: -­‐ Exchange Online Portal to view any latency created by accessing the portal -­‐ A trusted service on the Internet, like the Bing webpage -­‐ Intranet URL to measure internal network latency Analyzing the performance of these URLs and comparing that with the performance metrics of the other scenarios lets you drill down to the root cause of performance degradation. Exchange Online Performance Problems Performance problems with Exchange Online will be detected if the performance of various test scenarios drops while the performance of the Exchange Online Portal remains stable. In this case, you cannot blame your internal network or your Internet provider— decreased performance comes from Exchange Online itself.
    • www.gsx.com 11 Network Problem If you notice an increase in the latency of the Exchange Online Portal in conjunction with an increase of the number of scenarios you are running—and if you crosschecked that with an external website (e.g. bing.com)—then there is a high probability that the problem comes from your network. If you compare Exchange Online Portal’s latency with an internal URL, you will know if the problem comes from your Internet service provider. Otherwise, you may look for the problem on the network topology, network switch or other equipment. Exchange Online Upload Bandwidth Problems If the time to access the Exchange online portal rises with the scenarios in the same proportion, and your bing.com URL checks don’t have any problems, you will know that your infrastructure or Internet provider is not the problem. Most likely, bandwidth levels while uploading Microsoft online are the culprit. Measuring the Quality of the Network Infrastructure By looking at GSX as a user, you can place this user in multiple sites. For example, you can measure performance for users against an intranet page to check the performance of your own network infrastructure. Similarly, by checking performance against an external webpage, you can measure the quality of the service provider's network. What's most important in either case is to look at the variation of various metrics over time. 5- Monitoring and Troubleshooting Specific Users Performance and up-time can be extra-critical for some users, like executives. During and after the migration, it's important to ensure that these mailboxes are working within acceptable levels. If an executive does complain, you need to know if the lack of performance is real or perceived, and if the issue is ongoing or periodic. With GSX Monitor & Analyzer, you can measure the performance from a particular user's perspective, and detect whether the problem comes from the network, Internet connection or Exchange Online. 6- Analyzing the Performance and Comparing Sites GSX Analyzer allows IT administrators to access information about end-user performance through statistics, alerts and reports from anywhere. Access By Profile GSX Analyzer is based on profile access. This means that, as a super administrator of the platform, you can delegate access to multiple profiles which have different rights. For example, an IT administrator can give access to the Boston network administrator to the
    • www.gsx.com 12 statistics of his site, while you as a “super administrator” of the tool will have the ability to see and compare the performance of all the sites at the same time. Building Reports GSX Analyzer not only collects statistics about your cloud or hybrid environment, it’s also an easy-to-use and powerful tool to build automatic reports on the availability and performance of the service delivered by Exchange Online and your underlying infrastructure. Reports are configured in seconds and PDFs can be customized and sent automatically on a daily, weekly and monthly basis to multiple profiles (network, service management, IT management, etc.). Analyzing Trends GSX Analyzer allows you to view statistics in real-time in order to compare performance from multiple sites by detecting peak usage times and lack of performance, and by analyzing through URLs monitoring/multiples scenarios where problems arise, if any happen. Analyzer’s trends feature also allows you to create performance forecasts with just a single click. Moreover, GSX Analyzer provides you with an intuitive way to monitor your SLAs. The Environmental Health View provides instant templates that help you identify in seconds if one or several of your sites experience any performance problems. Analyzing Statistics Up and Down in Count Up and Down in Time The up and down in count are very important to follow. A down can last only a few milliseconds, however, even if these milliseconds minimally affect the overall availability, a down on a scenario means that the action was impossible to achieve. So, even if the down lasts a few milliseconds each time, from a user perspective the overall perception of performance will be seriously affected if you have too many down periods. That’s why trending these statistics for each scenario, simple or custom, is very important to have a clear insight on the user experience. You can also compare your number of downs from one site to another site that affect the overall availability of the Exchange Online services. Downtime should always be minimal. If you receive too many alerts about downtime from any GSX station, you should immediately open the monitoring console and check the last 3,000 scans to identify any recurring problem. To keep an eye on downtime from a wider perspective, you should run a report in Analyzer with the online scenario’s downtime compared to the downtimes of the Exchange Portal URL and a witness site.
    • www.gsx.com 13 5- Migrations – A Never-Ending Story There are various challenges you face when planning a migration and it can be a struggle to ensure security and effectiveness while maintaining productivity and avoiding major performance problems. Messaging systems have built-in tools that provide you with partial monitoring, but it’s critical to have a third-party tool to ensure that SLAs are actually met. 1- Using GSX Monitor & Analyzer to Prepare for a Migration to Exchange Online Any migration works more or less the same way. You need to know what you have, what you want to migrate, do the migration, and proactively fix problems which happen without any impact on the end users. GSX Monitor & Analyzer enables you to: • Prepare for your migration by understanding your current environment • Anticipate performance issues in the cloud and across multiple sites • Monitor user impact during the migration • Analyze the performance of the new environment Exchange Online Readiness Assessment • GSX automatically discovers your on-premises Exchange environment • GSX collects statistics about the usage of your mailbox (size, quota, location, logon, etc.) • GSX measures the performance of the service of your internal Exchange infrastructure • GSX evaluates the load of each server (number of connection, mail flow, etc.) • GSX measures the level of services delivered to the end users (through the end users’ scenarios) As GSX is completely agentless and easy to use, it only takes a matter of minutes to collect all of this information in a clear and understandable user interface which also allows you to predict your future needs (storage, load, performance, etc.). Pre-Migration Checks As GSX works exactly like a user, it should be the first user you move to your Exchange Online environment. GSX helps you prepare each site for migration to ensure that the Exchange Online migration will increase the availability and performance for each user.
    • www.gsx.com 14 Creating the First Couple of Monitored Test Users/Mailboxes per Site Each site that you want to check before migration should have a GSX scan engine installed to run scenarios on two different “monitored test users/mailboxes.” Why two? Because one of them will be migrated to the cloud. Then, you will have the exact comparison of the performance of the two users on-premises, and one user on-premises and the other one in the cloud. Checking the Ability of Your Infrastructure to Work with Exchange Online As you create two users on-premises, you can first perform the custom scenarios on them that will connect these two users: -­‐ Creation of a meeting with these two users involved -­‐ Mail routing between both Once you migrate one of these two users in the cloud, you can test—in advance and in real-time—the ability of your infrastructure to work with Exchange Online in a temporary or hybrid environment. You can trend the performance before and after the test migration to see if the interaction between these two users suffers. Comparing the Performance of Your Infrastructure with Exchange Online This is the point where it is highly recommended to configure basic scenarios, as well as custom scenarios, to measure the performance of your current on-premises infrastructure and Exchange Online. GSX will check the speed of attachment downloads, searches and meeting, email and task creation. Ensuring Mail Routing Performance It's critical to monitor mail routing performance in advance as it can cause serious bottlenecks during migration. To be sure that everything will work well from all the sites, you will: -­‐ Compare the performance of your on-premises mail routing with that of Exchange Online (on-premises to on-premises routing versus online-to-online routing) -­‐ Compare the performance of mail routing to and from the Internet by routing scenarios to an echo service from multiple sites, both on-premises and in the cloud.
    • www.gsx.com 15 Identifying Bandwidth Problems GSX will check the performance of your network and Internet provider through the URL monitoring. All the tests measure the quality of the network infrastructure, which will help you identify bottlenecks that could cause performance problems. Solving Performance Problems In GSX Analyzer, you can easily compare the performance of your on-premises monitored users with your new online monitored users in order to ensure that performance and availability will persist once migration is completed. As most potential problems can be detected before the migration with GSX, stress and costs linked to migration projects will decrease while ensuring user satisfaction and adoption of the new environment. 2- How to Monitor the Migration Itself? Migrating the “monitored user mailbox” gives you very important information about what you should expect from a user-performance perspective, and the capability of your on- premises infrastructure to work with Exchange Online without impacting users. In pre- migration tests, GSX checks that the users will be able to interact with each other, whether working from an on-premises environment or a cloud one. Finally, as GSX continues to check and collect statistics on your on-premises infrastructure, you will be able to monitor the reduced load on servers and ensure that everything works as expected for users who are still on-premises when you move online. 3- After the Migration After you have fully migrated to the cloud, GSX continues to ensure the performance and availability of service delivery from all sites and for all users.
