Planning service Yes
How the planning service works At Deep Sky Blue we provide highly experienced Business Analysts who work in close collaboration with customers to identify and understand the business objectives and benefits that will be realised by implementing or migrating services to the Cloud and from that derive a backlog of requirements. We bring our knowledge and understanding of data protection policies and can ensure the solutions we design are fully compliant with the relevant data handling legislation. Working in an agile way, our Architects and Lead Engineers bring their experience of developing cloud-native systems in some of the most secure and sensitive areas of government to ensure the solution design delivers on these benefits and meets the requirements. Continuing to work collaboratively with our customers, we then apply agile practices to forecast the delivery and produce a roadmap/plan which can be costed and clearly communicated to stakeholders as required. We understand how moving services and data to the Cloud can introduce risk. Throughout the planning process we will identify and quantify risks both from a technical and business change perspective and work with customers to agree treatment plans.

Setup and migration

Setup and migration
Setup or migration service available Yes
How the setup or migration service works Deep Sky Blue will provide Software Engineers experienced in designing, planning, implementing and migrating software solutions to the Cloud, be that public, private or hybrid.

We will work in an agile way, following a Scrum based delivery approach. This enables us to migrate or implement services in the Cloud in an incremental fashion, with regular demonstrations and testing of the benefits. This approach provides customers with full visibility of progress and the ability for them to validate and adapt the solution in line with feedback and testing.

Deep Sky Blue understand the benefits of being able to build, deploy and run applications, on any infrastructure in any type of environment, in a consistent and repeatable way. As part of this service our experienced engineers will bring their knowledge of Software Containerisation, both in terms of expert advice and hands-on technical implementation, in order to realise this benefit for our customers.

Our knowledge of legacy middleware platforms as well as our experience of working in complex environments with cross platform integration issues, enables us to design, plan and implement successful Cloud migration strategies for our customers.
Setup or migration service is for specific cloud services No

Quality assurance and performance testing

Quality assurance and performance testing
Quality assurance and performance testing service Yes
How the quality assurance and performance testing works We provide highly experienced ISTQB qualified Test Engineers who offer an independent and impartial approach spanning the full testing lifecycle.

We are committed to working closely with customers to understand business and technical risks, which underpins a risk based Test Plan that is jointly agreed. This testing model, coupled with our structured and methodical approach, provides a high level of assurance to ensure systems delivered meet the business need.

Our agile team of Test Engineers has a wealth of automation experience. Our DevOps delivery model follows an automation by default approach and ensures continuous testing is undertaken throughout the lifecycle to help improve the quality and speed of software delivery.

We bring experience across all aspects of performance testing in large and complex Cloud environments using a range of tools. Our Test Engineers also have experience of data migration and performance testing of legacy application and server migrations to the Cloud.

The key features offered by the DSB Test Service are:

Performance Testing (Load, Stress & Soak);
Test Automation;
Functional Testing (test design and execution);
Application and Server Migration Testing (functional and performance);

Support levels The levels of support we provide cover incident/issue response and incident/issue resolution, with resolution timescales based on the priority or severity of the incident. For incident response we have a target of responding to 90% of calls within 30 minutes. For incident resolution we have a target of resolving 90% of calls within the following timescales: Priority 1: 4 working hours, Priority 2: 8 working hours, Priority 3: 24 working hours, Priority 4: 40 working hours.

Our support costs are driven by the size of the team required to achieve the above targets and as such will depend on the scale and complexity of the cloud service/software we are supporting. We work collaboratively with our customers to agree an appropriate team size and then provide these teams in line with our G-Cloud rate card.

For all our Cloud support engagements we will provide a technical account manager who will have overall responsibility within Deep Sky Blue for delivering the service in line with the agreed service levels.
