How many of you are using IaaS today?How many of those are using public cloud? Anyone using anything other than Amazon? Anyone work for a service provider?Any interesting use cases that folks want to talk about?
Cloud Operators (Small Teams, Enterprise IT Department, Public Cloud Operators)Care about the underlying architectureOwe their users an SLAThe goal is to support their users in just the right waysCloud Users (Application Developers, IT Operations, DevOps Teams)Differing workload stylesCare about speed and flexibilityFocused on supporting the real end users…
The value of any infrastructure should be tied to the value that the applications running on it provide to the end usersOur project’s job is to make the operator happy, in service of the application owners, in service of the end users. While lots of hype surrounds the tech in this space, but that hype frequently does a disservice to the IT community by distracting from the end goal.
Empower users to “serve themselves”— removing IT from the critical path of the service deliveryAutomate previously labour intensive tasks, helping to reduce IT operation costs and deliver fasterReduces complexity and variability by using standard workloads which ensures consistency with each application and service deploymentRetains visibility into resource allocation and line of business usage on a real-time levelIncreased server/admin ratio and delivers benefits of scale— even if deployed globally
Don’t consider these numbers absolute in terms of installed clouds, instead focus on the correlation between the development and user community growth.Users in this context are primarily the operatorsThis level of correlation is a strong indicator of project longevity.
Dual Workload Support means:Choice of Hypervisor (or even Bare Metal servers)Choice in networking modelsChoice in storage typesChoice in Availability LevelsStrong ACL models to protect important applications from the “power” of automation to turn it off
Transcript of "CloudStack DC Meetup - Apache CloudStack Overview and 4.1/4.2 Preview"
What’s Apache CloudStack? Apache CloudStack is opensource software designed todeploy and manage largenetworks of virtual machines, asa highly available, highlyscalable Infrastructure as aService (IaaS) cloud computingplatform. CloudStack is a Top-LevelProject at the Apache SoftwareFoundation.
We Enable Cloud Operators To design, install, support, upgrade and scale their diverse cloudenvironments Application Owners To easily consume infrastructure services, so that infrastructuregets out of the way of delivering applications to the end users
So They Can EnableThe Application UsersYour end users want access to their applications,all the time from anywhere.They couldn’t care less about the environmentsupporting the apps they use…They care about the business results they achieveusing these applications.

Why do we care about the users? We are the users Builds the next generation of developers Drives project sustainability Improves quality
Users Driving the Project leads to Strong support for both traditional and cloud-era workloads Flexible deployment options and infrastructure choice Real-world experiences with scale Upgrades that work New technology integrations by and for the operators Testing of our APIs from diverse consumer tools
Infrastructure Model Management Server Farm Management and provisioning tasks Zone Collection of pods, network offerings and secondary storage Pod Collection of clusters in the same failure boundary Cluster A grouping of hosts and their associated storage Hosts Servers onto which services will be provisioned Primary Storage VM disk storage Network Logical network associated with service offerings Secondary Storage Template, snapshot and ISO storage ZoneCloudStack PodClusterHostHostNetworkPrimaryStorageVMVMCloudStack PodClusterSecondaryStorage
Deployment Architecture Hypervisor is the basic unit of scale. Cluster consists of one ore more hostsof same hypervisor All hosts in cluster have access toshared (primary) storage Pod is one or more clusters, usuallywith L2 switches. Availability Zone has one or morepods, has access to secondarystorage. One or more zones represent a cloudPod 1….Cluster NL2Host 2Cluster 1Host 1 PrimaryStorageZone 1….L3SecondaryStoragePod NManagementServerClusterInternet

Upcoming Releases4.1.0 - currently being voted on for release4.2.0 - entering feature freeze this week
What’s in 4.1? Lots of internal architectural changes (we want to speed updevelopment of new integrations) 20 new features 24 “improvements” 155 bug fixes
Architectural Changes Converted from custom injection framework to Spring Lots of refactoring: Storage plugin model Network plugin model API implementation refactored (remains compatible)There’s a theme here: We are making CloudStack moreflexible, both for developers and operators…
New Features in 4.1API, UI and Integration Options: AWS style regions Event pub-sub framework (RabbitMQ implementation) Advanced search within the UI API Server request throttling API Discoverer Service Users resetting their own passwords Users directly changing their API keys EC2 query API Cloudmonkey CLI
New Features in 4.1Networking: Nicira integration adds L3 functionality Persistent networks without a running VM Autoscale (Netscaler implementation) Juniper SRX & F5 Big IP inline mode Egress FW rules for guest networks Open vSwitch support for KVM
New Features in 4.1Compute: Support for passing custom VMX settings to vSphere on VMcreate Adding and removing Virtual NICs from VMs Reset SSH key within a VMStorage: Volume resizing S3-backed secondary storage
Great, That’s 4.1…What about 4.2? Many features proposed for 4.1 were moved to 4.2(Remember that time-based release thing?) 58 New Features scheduled for 4.2! 16 of them are already finished, including testing Some of them won’t make the release (again, time-based!) 40 Improvements (same caveats as features)
Sample 4.2 Features Midonet and BigSwitch SDNintegrations Enhanced Baremetal provisioning VM I/O Throttling Hyper-V 2012 Support LXC Support Cisco VSG integration Cisco ASA 1000V VM Affinity Rules Eliminate NFS layer for S3 secondarystorage Zone-wide primary storage Security group isolation in AdvancedNetwork zones Dedicating resources to domains andaccounts IP Address reservation w/o a vNICallocation Improved synchronization betweenCloudStack and what’s actually runningon the hosts vSphere DVS support UI Plugin framework
