MDS AND SKYSCAPE – THE PERFECT PARTNERSHIP

MDS technologies Limited (MDS) offers a cloud platform provided by the award winning Skyscape

Cloud Services (Skyscape). We have a strong, committed relationship with Skyscape, the market

leader in the Digital Marketplace for G-Cloud Infrastructure as a Service, through a long-standing

relationship underpinned by a formal partnering agreement. We have been a Skyscape Partner since

their creation in 2011, and have resold services since the launch of the G-Cloud framework in

February 2012. MDS is a reseller, at cost, of Skyscape’s cloud services and is currently Skyscape’s

largest partner and second largest consumer of cloud services. This status enables us to provide a

high level of service to our customers and gain enhanced support from Skyscape.

As a Skyscape partner, MDS offers true National Institute of Standards and Technology (NIST) cloud

services, which are offered as part of a community cloud service only available to the UK Public

Sector and secured and managed in line with UK government security classifications.

Skyscape and MDS both utilise pricing models based on transparent charges and “pay for what you

use” on an hourly and/or monthly basis.

Figure 1. Solution elements

This service is targeted at data scientists as a data platform service, rather than at end users who

usually expect a complete SaaS analytics solution. Data scientists can use the Skyscape service to

build higher-layered services for end users. They can rapidly provision capacity optimised for Hadoop

to support data-intensive tasks such as indexing, mining, analytics and so on (orange components in

Figure 1).





What the service can help you achieve

Reduce the capital expenditure risk typically associated with exploring big data by using the flexibility of a cloud service

Reduce storage cost and complexity by consolidating disparate data stores into a central location, while facilitating holistic analytics across the widest possible dataset

Enable analytics across multiple organisations’ datasets by creating a shared data repository

Create a data store capable of handling high-volume, high-variety and high-velocity data (for example, social media sentiment analysis, IoT sensor data, large machine–generated/sensor data) that exceeds the capabilities of traditional database technologies

Create a cost-effective and future-proof environment to meet the ever-growing storage demands of modern analytic requirements

Key service capabilities

Choice of the most popular 100% open-source Hadoop distributions — Cloudera Enterprise or Hortonworks HDP

A true on-demand OPEX-based service which eliminates traditional CAPEX challenges

A fully configured deployment which helps reduce the level of expertise needed to get started with the fundamentals of Hadoop

Removal of the capacity management burden traditionally associated with Hadoop

An extensible solution which enables you to use any Hadoop-compatible business intelligence, analytics and reporting applications

Uncontended resources reduce any adverse performance issues as a result of noisy neighbours

Proximity of Hadoop data to compute resources increased processing performance and removes data transfer charges between compute and storage

An unrivalled big data and analytics partner ecosystem

Independently audited and verified by trusted public sector organisations, including HSCIC (NHS Digital), MoJ and the Police (Police Approved Secure Facility — PASF), for workloads requiring a higher assurance for sensitive data (for example, MoD Defence-as-a-Platform)

UK sovereignty — assured cloud platform delivered by a UK-based company with UK government security-cleared staff

Platform that hosts workloads exclusively for the UK public sector, creating a known and trusted community of neighbours





Cloud characteristics delivered

Elasticity — scale your big data solution using the Skyscape Portal or our fully documented API

Self-service — rapid availability on both our Assured and Elevated domains means zero delay to your project

Measured usage — from just 45p per useable TiB per month for HDFS storage

Broad networking — connect via DDoS-protected internet, a government community network, or HybridConnect using your own dedicated circuits

Resource pooling — a neutral platform, shared with a trusted community of UK public sector users to facilitate interconnected datasets

Key characteristics of our service

Our Hadoop in the Cloud service offers a distinctive mix of multi- and single-tenant elements in its

infrastructure to deliver the highest levels of performance and security, without sacrificing the

commercial benefits or flexibility of the cloud. Each cluster is deployed on Hadoop-dedicated

and -optimised multi-tenant infrastructure, with the following single-tenant elements:

Single-tenant cluster. Each customer is provisioned with their own isolated Hadoop environment — virtual master nodes, virtual slave nodes and virtual cluster managers aren't shared with any other tenants.

Dedicated 1:1 mapping of slave nodes to directly attached physical drives helps increase overall HDFS performance and security.

Skyscape uses either VMware vSphere or OpenStack for the underlying IaaS service, with customers

choosing Cloudera Enterprise or Hortonworks®

HDP deployed on top as the enabling Hadoop

distribution. The table gives an overview of each distribution.

The platform consists of the following modules and associated supporting services:

Hadoop Common: the common utilities that support the other Hadoop modules

Hadoop Distributed File System (HDFS™): a distributed file system that provides high-throughput access to application data

Hadoop YARN: a framework for job scheduling and cluster resource management

Hadoop MapReduce v2: a YARN-based system for parallel processing of large datasets

Hadoop Zookeeper — a distributed transaction coordinator

The Hadoop core platform facilitates data ingress and egress along with native MapReduce v2

applications. In addition, we provide access to Hadoop cluster management via API or GUI

Cloudera Enterprise

Based on ApacheTM

Hadoop — 100% open source

Cloudera Impala — industry-leading massively parallel (MPP) SQL engine built for Hadoop

Cloudera Search — advanced query and data-browsing capabilities

Certified on Skyscape’s Platform

Support included

Hortonworks® HDP

Based on ApacheTM

Hadoop — 100% open source

Free-to-use enterprise distribution and features (without support)

Support subscriptions available directly from Hortonworks®





(depending on the chosen distribution — Cloudera Manager or Ambari), for you to use to manage and

maintain your entire Hadoop cluster.

We monitor all VMs and services related to the embedded Hadoop core platform as defined above,

and provide 'reasonable endeavours' support for all associated services.

We provide a secondary virtual data centre (VDC) alongside the Hadoop cluster to enable customers

to deploy their own analytics, business intelligence and reporting applications. We charge for and

support any VMs within this secondary VDC in line with our Enterprise Compute Cloud or Cloud

Native Infrastructure service definitions. However, Skyscape isn't responsible for managing any

image, software or service deployed within these VMs.

Figure 2. Hadoop in the Cloud overview

This service is extensible, as shown in Figure 2, allowing additional analytic applications to be

deployed to facilitate functions beyond data ingest, egress and MapReduce v2 jobs. These depend on

the choice of distribution and may include:

Cloudera Impala — a massively parallel processing (MPP) SQL query engine

Cloudera Search — for non-technical users to search and explore data

ApacheTM

Spark — an in-memory data store

ApacheTM

Falcon — for data management and pipeline processing

ApacheTM

Kafka — a fast, scalable, durable, and fault-tolerant publish-subscribe messaging system

Management and maintenance of any additional applications deployed by the customer, beyond the

initial deployment, remain the responsibility of the customer or third party.





Pricing and packaging

To maximise cost flexibility against user requirements, we offer three Hadoop cluster types for you to

choose from, based on your initial data requirements, coupled with your projected rate of future data

ingest. See the table below.

Cluster type Use case Master node spec Slave node spec

Low Velocity Proof of concept / small data projects

9 vCPU

60GiB RAM

500GiB disk

120GiB RAM

1000GiB disk

36 vCPU

240GiB RAM

200GiB disk


Backup/recovery and disaster recovery

The Hadoop storage engine, HDFS, is engineered with infrastructure failure in mind, so localised

component failures are tolerated within the infrastructure via data replication, eliminating single points

of failure (including physical server failure or disk failure).

Hadoop v2.4.1+ allows for the manual creation of snapshots of HDFS, which can be stored offline

using Skyscape’s Cloud Storage.

Pricing

Skyscape’s Hadoop in the Cloud lets customers scale up HDFS storage resources as required, yet

retain elasticity around analytics requirements. Each cluster will initially be provisioned with a Starter

Pack (defined below), after which customers are free to scale their cluster by adding additional slave

nodes.

Starter Pack Additional slave node (above Starter Pack)

Cluster type TiB capacity (usable†)

Cost (£) per hour TiB capacity (usable†)

Cost (£) per hour

Assured Elevated Assured Elevated

Low Velocity 10 £4.50 £5.50 3.333 £0.80 £0.95

Medium Velocity

20 £5.50 £6.50 6.666 £1.30 £1.50

High Velocity 40 £8.50 £10.00 13.333 £2.00 £2.40

Notes:

†Usable capacity reflects HDFS storage including the default data replication factor of three

(raw capacity is three times greater)

Licensing is not a mandatory Skyscape requirement, so pricing does not include Cloudera or Hortonworks licensing (where applicable) or support subscriptions. You can get prices for these services through a direct arrangement with either vendor via the Digital Marketplace





It is currently not possible to mix and match cluster node types within a single cluster (for example, a Low Velocity cluster can only scale out with Low Velocity slave nodes)

Additional slave nodes can be expanded in single units as shown above

All pricing is charged per hour or part thereof

The pricing for the following items is given in the Skyscape Pricing Guide:

Enterprise Compute Cloud

Cloud Native Infrastructure (Powered by OpenStack)

Mass Transfer Facility data ingestion and extraction

∆ Comparative

Starter Packs

To ensure the correct resources are initially deployed to provide a stable Hadoop cluster, we will

provision the following virtual nodes, configure the networking and deploy your choice of Cloudera

Enterprise or Hortonworks HDP. A Starter Pack consists of the following:

3 x master nodes (Name Nodes, Zookeeper Master, additional master services)

3 x slave nodes (HDFS storage and applications)

The specification for each master/slave node will be in line with the cluster type you select, as defined

above.

Support subscriptions

We manage the resources required to ensure the availability of our Hadoop core platform, but we

don't manage the analytics or software stacks that sit above it. Unless your organisation has

embedded Hadoop expertise and experience, we strongly suggest you purchase a support





subscription for your selected distribution to help you with support and usage issues beyond our

Hadoop core platform.

Additional Hadoop distributions

You can deploy on Skyscape’s IaaS and manage your cluster directly or via a partner (for example,

you may deploy PivotalHDTM

Enterprise edition, MapR or IBM BigInsights on Skyscape IaaS and get

support directly from Pivotal®).

Selecting a partner (optional)

Customers who have (or are developing) in-house skills and experience with Hadoop should be able

to benefit from using this service directly. However, customers requiring a service that provides

business intelligence or data analytics will need to engage a specialist partner to build those layers on

top of Skyscape’s Hadoop in the Cloud.

Skyscape can introduce you to partners in our Partner Programme who offer appropriate specialist

consulting services through G-Cloud.

You may also choose to work with a specialist partner for enablement services; or to use software

services that need licences or support subscriptions.

For clarity, we don't mandate the use of partners or the requirement to procure licences/subscriptions.

Connectivity options

Skyscape provides one of the best connected cloud platforms for the UK public sector. We offer a

range of flexible connectivity options that enables access to our secure platform by virtually any

community of government users and systems. The variety of government, public and private networks

is shown in the following diagram:

In addition, you will be assigned a Customer Success Manager (CSM) to provide any assistance required during the first 90 days of the service.

Skyscape also has a large ecosystem of partners who can deliver additional services such as training, support and professional services. Skyscape would be pleased to introduce you to the right partner to suit your needs.

Data migration

In many circumstances, Skyscape can help facilitate a bulk migration to the platform using local data import. This is priced on a time-and-materials basis from the Skyscape SFIA rate card.

Skyscape can also help facilitate a bulk migration to the platform using offline data ingest and extraction — please ask Skyscape for details.

Service management

As a true cloud service aligned to the NIST definition of PaaS, the service is designed to be self-managed via the Skyscape API and secure online Portal which provide common service management functionality and address standard requirements.

Skyscape will allocate a Technical Account Manager (TAM) to provide you with an assigned point of contact. The TAM will provide additional assistance with reporting and incident escalation, at all times following Skyscape’s ISO 20000-certified ITIL-based process framework.

For organisations that require a managed service, Skyscape has a mature and active partner ecosystem that can provide value-added services such as consultancy, training and ongoing custom managed services. Skyscape will be pleased to make an introduction on request.

Service constraints

Skyscape Hadoop in the Cloud is engineered to be scalable and has been tested up to 850TiB HDFS cluster storage. We advise consulting with Skyscape if you need to scale beyond this capacity

Skyscape will adhere to the following in terms of maintenance windows:

“Planned Maintenance” means any pre-planned maintenance to any of the infrastructure relating to the service. Planned Maintenance activity may result in periods of degradation or loss of availability depending on the nature of the activity required. In such cases, Skyscape shall provide affected customers with at least fourteen (14) days' advance notice of the Planned Maintenance.

If during Planned Maintenance there is a loss of availability outside the scope described in the planned maintenance notification to the service, an SLA event will be triggered, but excluded from Service Credits.

“Emergency Maintenance” means any urgent maintenance required to prevent or mitigate against any event compromising the infrastructure relating to the service. Whenever possible, Skyscape shall: a) provide affected customers with at least six (6) hours’ advance notice and b) carry out the emergency maintenance between the hours of 00:00 and 06:00 (UK local time) Monday to Sunday or between the hours of 08:00 and 20:00 (UK local time) on Saturday, Sunday and bank holidays





unless there is an identified and demonstrable immediate risk to customer environment(s). Emergency Maintenance may result in periods of degradation or loss of availability depending on the nature of the activity required.

If during Emergency Maintenance there is a loss of availability to the service, an SLA event will be triggered. This time will be excluded from the availability calculation but will be included in monthly service reporting related to the service.

Technical requirements

Customers will require appropriate network connectivity such as internet access or accredited connectivity such as a government secure network to the Skyscape cloud platforms. Connectivity via the internet, a government secure network (PSN, JANET or N3) or private leased line is available but may incur additional charges if the hosting of CPE routers is required — see the pricing section for more details. Where they are required, customers are responsible for procuring and managing appropriate devices or software to meet the requirement for data security over the various forms of connectivity.

Customer responsibilities

The control and management of access and responsibilities for end users including appropriate connectivity, security and accreditation if required. If access is required over government secure networks such as N3, JANET, RLI or PSN (including legacy networks), the customer is responsible for adhering to the Code of Connection.

Management configuration and administration of layers above the PaaS Hadoop core platform (for example data ingest, analytics jobs, visualisation, tool selection).

Customers must be aware of the variable nature of the billing based on usage.

Customers are expected to maintain a master copy or backup copy of the data used in the Hadoop in the Cloud service.

The customer is also responsible for ensuring only appropriate data (for example OFFICIAL) is stored and processed by applications on this environment and that they comply with the Skyscape Security Operating Procedures (SyOps) and other information assurance requirements as specified in the Skyscape System Interconnect and Security Policy (SISP) and associated accreditation documentation sets

Termination

Terms

Customers can terminate this service by providing Skyscape with not less than 30 days' advance notice in writing.

At the point of termination, all customer data, accounts and access will be permanently deleted, and will not be able to be subsequently recovered or restored.

Costs

There are no termination costs for this service. Customers are responsible for extracting their own data from the Hadoop platform if required.

Skyscape may make an additional charge for transferring data out of the service.

Offboarding

Customers are expected to maintain a master copy or backup copy of the data used in the Hadoop in the Cloud service. So there is no requirement for the customer to transfer their data out of the solution at the end of the contract. Rather, the customer simply has to securely delete the data prior to the termination of the contract
