8 ShareFile High-level Architecture

9 ShareFile – with Citrix managed StorageZones
DB *.sharefile.com *.sf-api.com Control Plane Account info Brokering Reporting Access Control Client Storage Center (EC2) S3 StorageZones Storage Centers Backend Storage Various Locations WW ShareFile’s high-level architecture basically consists of 3 different components. There is the client, accessing the ShareFile service through one of the native tools, Citrix Receiver a browser or directly through the API. <CLICK> There is the Control Plane, which performs functions such as storing file, folder and account information, access control, reporting an various other brokering functions. <CLICK> And then there is the Storage Plane, which is where the actual customer files are hosted. <CLICK> Clients communicate with both the Control Plane and the Storage Plane, <CLICK> and the Control Plane and the Storage Plane communicate as well <CLICK>, but customer files will never travel from the Storage Plane to the Control Plane. In a couple of slides we will look at this in more detail. <NEXT SLIDE>

10 ShareFile – Current Architecture
With Citrix managed StorageZones

11 ShareFile Control Plane
No Client Files File Metadata Account Data DMZ Webservers “main app” Load balancing Client SQL Cluster Load balancing TLS/SSL AES-256 Encryption API Webservers Replication to DR Datacenter Let’s take a more detailed look at the ShareFile Control Plane. <CLICK> The ShareFile Control Plane is hosted in Citrix Online’s datacenter. In the datacenter we have the following components: <CLICK> There are webservers both for our Web UI, also called the “main app” <CLICK>, as well as dedicated webservers for client devices using the HTTPS API, which is being used for our various client tools. <CLICK> <CLICK> Of course there is the Database, running on an SQL Cluster. <CLICK> The database contains things such as account data, file and folder metadata, including access rights, user account data, logs etc. etc. The Database in the Control Plane does not contain any customer files. <CLICK> Note that we will only store hashed user passwords in the database. Client requests are distributed across the webservers using NetScaler. <CLICK> The NetScaler and webservers are running in the DMZ and the Database cluster itself is in the production network behind the firewall. Now let’s see what happens when a client device goes to the main app or one of our client tools connects to ShareFile. <CLICK> Of course there is the Client device on the outside of the network. <CLICK> The client connects to the Control Plane using 256-bit encryption. <CLICK> The NetScaler loadbalance the traffic across the webservers. <CLICK> And the webservers communicate with the database to retrieve the requested information. <CLICK> The database itself is also securely replicated to a second datacenter for backup and Disaster Recovery purposes. <NEXT SLIDE>

The 2 main places where files are stored are Elastic Block Storage for caching purposes in EC2 <CLICK>, and the storage in S3 for persistent storage. <CLICK> Now let’s take a look what actually happens when a user uploads a file to ShareFile. <CLICK> Of course there is the Client device on the outside of the network. <CLICK> For regular uploads the Client connects to the Storage Center using 256-bit encryption. <CLICK> If a file is being uploaded through FTP or FTPS, there is no direct connection to the Storage Center. But the client connects to one of the FTP servers, <CLICK> which communicates with a Storage Center server. <CLICK>The Storage Center encrypts the file and places the file in the local cache, which is kept on the attached EBS disk. At the same time the file is being put in the storage queue for committing to the persistent S3 storage, <CLICK> which is a continuous process that runs on the Storage Center. The files remain encrypted during this process. <CLICK> The Utility Servers communicate with the Control Plane and know about new files being uploaded and will fill up their respective queues for files that require Anti Virus scans, thumbnail creation, full-text indexing, backup etc. <CLICK> Files on S3 will be processed based on their place in the queue. The SLA with Amazon guarantees 99.99% availability, and a “12 nines” file durability against file loss. <CLICK> Amazon takes care of this in the back-end. <CLICK> Finally we also create a backup of all encrypted file data in a 3rd party datacenter. <CLICK> The backup server communicates with special Backup utility servers in EC2 <CLICK> and will backup files from S3. <NEXT SLIDE> EC2 S3

13 ShareFile StorageZones - Download
FTP/FTPS FTP Servers Client Storage Storage Centers Storage TLS/SSL AES-256 Encryption EBS Elastic Block Storage When a client downloads a file, the file will be served out of local EBS if in cache <CLICK>, otherwise it will be served from S3 storage <CLICK>. The file will be decrypted by the Storage Center and send to the client over an encrypted connection. <CLICK> Or if downloaded through FTP or FTPS, it will be send to the client through the FTP Servers <CLICK> <NEXT SLIDE> EC2 S3

14 Availability and Redundancy

15 Availability Information
Real-time backup to Citrix data center Automatic failover (if necessary) Lazy file deletion to support file recovery Control subsystem has DR location in Las Vegas Files backed up to facility in Charlotte NC

Now available for all ShareFile Enterprise accounts Store files in customer-managed StorageZones, in Citrix-managed StorageZones or both Technology proven in the Cloud Seamless user experience Modified On-Prem version of existing Storage Plane software Proven technology Same user experience Seamless for users, they don’t know where there files are being stored

18 Compliance Performance
Why StorageZones? Compliance Performance Meet unique compliance and data sovereignty requirements by storing data On-Prem Optimize end user performance by placing files and folders in close proximity

DB *.sharefile.com *.sf-api.com Control Plane Account info Brokering Reporting Access Control Client StorageZones Storage Center (Windows IIS) CIFS Storage Center (EC2) S3 Storage Centers Backend Storage In customer Datacenter(s) Hybrid with cloud The architecture with our recently announced StorageZone technology with on-premise data option is similar to what we have today with our pure Cloud offering. The Client side and the Control Plane are the same. The difference however is in the Storage Plane. If you chose to use the on-premise option, you will have what we refer to as a local or on-premise StorageZone. This StorageZone has one or more Storage Centers, which are installed on Windows 2008 Servers with IIS and utilize local NAS storage. The StorageZone components run inside the customer’s Datacenter. “Mix and match” is a possibility as well, where you have certain files in your own datacenter and certain files in a Citrix, cloud-hosted StorageZone. Client connectivity and communication are the same as in the Cloud model. No customer files will go through the Control Plane We will talk more about StorageZones and on-premise storage later on.

36 Troubleshooting StorageZones

37 Basic Troubleshooting
Ensure you type <external address> without port or https & check for typos on Configuration Page Ensure on Enterprise account with SZ Make sure user account has SZ admin permissions Check if Storage Center URL is accessible from outside Check file share for creation of directories Check if SCKeys.txt is created in root of file share Logs!

When the client requests a file for download a prepare message is send by the main app or the API servers in the Control Plane to the Storage Center hosting the file. The location of the file is stored in the DB in the Control Plane, which is where the main app and API servers get this information. An HMAC based on the Shared Key used to establish a trust relation between the Control and Storage Plane, is being send as part of the prepare message and is validated by the Storage Center. Once validated, the Storage Center confirms the validity and the Main App or API server will provide the download link to the Client with a unique HMAC. To start the actual download, the Client will now connect to the Storage Center. Again, an HMAC, which is part of the download request from the Client, is being validated and if successful, the file will be retrieved from storage, either from cache or S3 and the Storage Center will provide the file to the Client Shared Secret (trust)
