Introduction
Symantec
- Symantec is the world leader in providing security software for both enterprises and end
users
- There are 1000’s of Enterprises and more than 400 million devices (Pcs, Tablets and Phones)
that rely on Symantec to help them secure their assets from attacks, including their data
centers, emails and other sensitive data
Cloud Platform Engineering (CPE)
- Build consolidated cloud infrastructure and platform services for next generation data
powered Symantec applications
- A big data platform for batch and stream analytics integrated with both private and public
clouds
- Open source components as building blocks
- Bridge feature gaps and contribute back

Big Data Platform Challenge
• Hundreds of millions of users generating Billions of events every day from
across the globe
• Hundreds of Big Data Application Developers developing 1000s of
applications
• At 12 PB and 500+ nodes, Cloud Platform Engineering Analytics team built
the largest security data lake at Symantec
• Elasticity is built into the platform to optimize costs in the cloud

• Great! Now Developers can start building applications on our
Big Data Lake
• 100s of developers start building applications using different big
data tools

• Product team developers wants quick changes, latest versions
• Platform team wants stability!
• Soon, frustration prevails

What is the Solution?
• Build and use your own little cluster for development
• Copy subset of data for development purposes
• Build elasticity into the platform for cost optimizations
• Tear down the cluster after development is complete
• Repeat and Rinse

What is the Solution?
• But Building clusters are hard and time consuming
• Too many services to install and configure
• Developers are not interested in building and managing clusters

What is the Solution? – Self Service
• What if we make it really easy to build clusters?
• Abstract all the deployment complexities and enable developers
to get their own cluster in one click of a button
• Use the same blueprint for both dev and prod clusters

Self Service Analytics (SSA) Clusters
• RESTful web services to allow creation and management of
custom clusters
• Select from pre-defined Ambari Blueprints
• Can provision infrastructure on Openstack as well as AWS
• Installs HDP stack specified as part of Ambari blueprint
• Dashing dashboard to monitor and manage (start/stop/kill)
clusters

Environment
• Private cloud on Openstack (Kilo, No Heat)
• Public cloud on AWS
• HDP 2.3.2 & 2.4.2
• Ambari 2.1.2 & 2.2

SSA Architecture

SSA Services

SSA Demo

Ambari Custom Services
• What about the services that are not supported by Ambari out
of the box?
• We write our own Ambari custom stack

Next Gen SSA
• This is all great! But, lot of work to add more cloud providers.
• Takes a lot of effort to understand the cloud provider’s APIs

Next Gen SSA – Cloudbreak
• Cloudbreak
–Cloudbreak helps to simplify the provisioning of HDP clusters in cloud
environments
–Supports multiple clouds including AWS, Google, Azure and Openstack
–Uses Apache Ambari for HDP installation and management
–Has a nice UI to build and manage clusters
–Supports automated cluster scaling

AWS Cluster Architecture
Private Subnet
 Direct Connect
 10 Gbps
 Data Ingestion Pipes
 Telemetry Ingestion Pipes
 Datacenter hosts HDP over
bare-metal and Openstack
 Uses d3.* and r3.* flavors
 Encrypted volumes – LUKS
 Non-EBS root volume
 Non-Dockerized HDP
 Custom AMI
 Enhanced networking

Cloudbreak Demo

Hybrid Cloud Using Cloudbreak – Customization &
Contribution
• Non-dockerized HDP installation
• Support for Keystone v3 for Openstack
– Cloudbreak 1.2 – released 03/2016
• Support for Custom AMIs
• We have our own hardened images with Enhanced Networking, Volume Encryption, etc
• Support for non-EBS backed root volumes
• Deploy in existing private VPC/Subnet
• Additional AWS instance flavors supported
– We use r3.* and d3.* which are not supported by Cloudbreak
• We build our own Cloudbreak package from the trunk

Custom AMI Support
•Org security mandates using specific
hardened AMIs only
•Created our own hardened image with
software and configurations required by
Cloudbreak
•Allows us to use features like:
–Volume encryption, enhanced networking enabled
–Non-EBS volumes
–Symantec specific configurations like LDAP, repos, DNS etc
–Symantec standard for hostnames
•Use jdk1.8 instead of java 7 which comes with
Cloudbreak AMI
/cloud-aws/src/main/resources/aws-images.yml

Non Dockerized HDP Support
Why?
•No experience running production clusters under docker.
•Unknowns with upgrade path for HDP components.
•Encrypted Disk Volumes had issues working with docker.
What?
•Worked with Cloudbreak team to test out non-Dockerized version of
Cloudbreak
•Provided feedback from our test deployment of the non-Dockerized version
•Feature now available in the master branch

Non-EBS backed root volume
•Changes to AWS CloudFormation template used by Cloudbreak
•We use ephemeral storage for root volumes for availability
reason
•Will contribute this back as an option to Cloudbreak

Cloudbreak Contribution – In Progress
•Placement groups
•Multiple security groups attached to one cluster
•Multiple subnet deployment inside VPC
•Support for non-EBS root volumes

Monitoring & Alerting
Now that we have delivered an elephant, the next question from
users is – How is his health?

Monitoring and Alerting
•Comprehensive dashboards for all environments managed by
the platform team
•Extensively use Ambari Alerts
•QueryX: Custom framework to fill the gaps in Ambari Alerts
•All alerts are sent to OpenTSDB + Grafana stack
•Critical alerts – PagerDuty

Summary and Future Work
• A journey towards one click cluster deployment
• Cloudbreak - one tool for all cloud
- Contribute back the features developed in-house
- Enable Cloudbreak to support Baremetal cluster provisioning
- Auto-scaling using Cloudbreak and Periscope
- Single large YARN cluster for variety of compute and storage loads
• Open source – use and contribute
- Work with community to address gaps
• SSA code already opensourced
