However, achieving it is no small accomplishment. In the design of VOS Cloud, we spent a lot of time thinking about the things that can go wrong and addressing them in every part of our application. This article details how we tackled the various potential problems and aims to educate&nbsp;our customers on what options are available to them to optimize failure recovery to meet their business needs.<br /><br /> Perhaps the best place to start this discussion, surprisingly enough for a cloud native software application, is by talking about hardware and hardware topology of the cloud.<br /><br /> <u><b>What is an Availability Zone?</b></u><br /><br /> An Availability Zone (AZ) is an isolated location inside a region (ex: datacenters, racks, power strips,etc.). Each AZ belongs to a single region and is connected through low-latency links, which have a separate fault domain, such that failure in 1 zone would not impact another, as illustrated in the diagram below. While at the same time, connectivity between zones should be fast to ensure no performance impact among zones.<br /><br /> <img src="https://d2r1vs3d9006ap.cloudfront.net/s3_images/1553107/27030-18ez1ou_inline.png?1487282536" title="Image https//d2r1vs3d9006apcloudfrontnet/s3_images/1553107/27030-18ez1ou_inlinepng1487282536" /><br /><br /> Although rare, failures can occur that can affect the availability of instances that are in the same location. If you host all of your instances in a single location that is affected by such a failure, none of your instances would be available. If you distribute your instances across multiple AZs and one instance fails, you can design your application so that an instance in another AZ can handle requests as an emergency back-up.<br /><br /> When building a cloud, you usually define two or more AZs inside the datacenter. Examples of AZs are servers on:<br /><br /> <ol><li>Different power lines feeding the datacenter</li><li>Different blade enclosures</li><li>Different rooms inside the datacenter</li><li>Different buildings</li><li>Etc....</li></ol> We have built our application to take advantage of the AZ construct as built into AWS and OpenStack. An AZ is an&nbsp;attribute that can be attached to compute nodes.<br /><br /> <u><b>Using Mesos as an "Availability Zone Aware" Hardware Schedule</b></u><br /><br /> Mesos, a hardware scheduler, is aware of the different AZs. Queried through metadata&nbsp;Application Programming Interface&nbsp;(API), this is a standard service provided by AWS/OpenStack. When we launch Mesos on each of the nodes, we pass a parameter to Mesos to notify it that the current nodes are running at this AZ. Within VOS, we tag certain tasks to be run in separate AZs if they are present. Each processing node in the system is tagged with its AZ.<br /><br /> <u><b>How Many Availability Zones Can We Support in AWS and OpenStack?</b></u><br /><br /> On AWS, we can launch EC2 instances into at least 2 AZs, but can support up to 4. While on OpenStack, the number of AZs we support depends on how you configure your OpenStack. We use AZ information for providing HA, by distributing redundant tasks across different AZs.<br /><br /> <u><b>Which Services in VOS are “Availability Zone Sensitive”?</b></u><br /><br /> All services and tasks that have redundancy can utilize AZ information.<br /><br /> Within VOS we tag certain tasks to be run in separate AZs if they are present. The means for which this is achieved is similar between AWS and OpenStack. Each processing node in the system is tagged with its AZ. When tasks are spun up, there are rules about certain tasks running in the same AZ.&nbsp;Examples of these are:<br /><br /> <ul><li>Redundant transcoding which run in different AZs.</li></ul><ul><li>VOS HA Process: the primary access to the VOS Cloud system is the API. Perhaps you only use the User Interface, but this is built on top of the API. In fact, both of them are served by the same Web Server. Therefore, loss of access or failure of this component would leave you unable to configure the system or see if it is healthy, but would not stop any of your services that are running, or impact the rest of the HA of the rest of VOS Cloud.</li></ul> question 0 1 1 create http://m.getsatisfaction.com/topics/7031773 7031773 Achieving High Availability in VOS Cloud - Part 2 (Service Redundancy) 2016-06-17T18:21:29Z 2016-06-17T18:21:29Z Yaniv Ben-Soussan http://m.getsatisfaction.com/people/8158510 https://d2r1vs3d9006ap.cloudfront.net/public/uploaded_images/10798104/yoda-06_medium.jpg yaniv_ben_soussan For an application processing linear video services, High Availability is a key requirement.

This article details how we tackled the various potential problems and aims to educate&nbsp;our customers on what options are available to them to optimize failure recovery to meet their business needs.<br /><br /> As we learned in part 1 of "Achieving High Availability in VOS Cloud", VOS is aware of the different Availability Zones of the cloud deployment environment, and will take advantage of it.<br /><br /> VOS is offering 2 levels of service redundancy as described below:<br /><br /> 1. <b>Hot - Hot (1:1)</b> - When you turn ON redundancy for a service (see below), VOS will stage two copies of the same service, in two different availability zones inside the VOS cluster. That also means VOS will consume double the resources (compute and network) of a given service.<br /><br /> In this mode the redundancy fail over will be less than 1&nbsp;second.<br /><br /> <img src="https://d2r1vs3d9006ap.cloudfront.net/s3_images/1442087/4322-1wl7e6w_inline.png?1467323397" title="Image https//d2r1vs3d9006apcloudfrontnet/s3_images/1442087/4322-1wl7e6w_inlinepng1467323397" /><br /><br /><br /> Figure-1: Output Service under the Configure application<br /><br /> 2. <b>Best effort </b>- As VOS is a self-healing cloud base application, even when redundancy is turned OFF, VOS will try to re-establish the services on residual resources on an available VOS nodes.<br /><br /><br /> In this mode, the redundancy fail over will be ~10 seconds. question complete 0 1 3 create http://m.getsatisfaction.com/topics/6995948 6995948 What is the difference between VOS 360 and VOS Cloud?

But whenever a new property or feature is added to the profile, the Harmonic version number is changed to the next whole version number (for example: 1.0 or 1.3 becomes 2.0).<br /><br /><b><br />How are streams handled in VOS?</b><br /><br />A stream being processed can either be transcoded, or “passed through” to the output without processing.

When editing the values of the fields on the right, you enter the manual mode. All fields are shown and can be edited. Click Parametric mode to return the profile to a state in which you can edit for instance the Audio section on the left.&nbsp;<br /><br /><b><br />How can you enter/exit the manual editing mode on the Multiscreen profile?</b><br /><br />When you have the Multiscreen profile open, clicking on the Audio section on the left, results in the display to the Audio fields on the right for the different defined output profiles. When editing the values of the fields on the right, you enter the manual mode. All available output profiles with their fields show and can be edited. By clicking X in the right top corner of the fields, you return the profile to a state in which you can select for instance the Endpoints section on the left.<br /><br /><b><br />What push packages are available?</b><br /><br />Available push packages are: HLS (Apple), DASH (Consolidated Delivering), and MSS (Microsoft Smooth Streaming). question complete 0 1 1 create
