Cloud & Infrastructure
Harmonia’s comprehensive experience starts with facility planning and infrastructure, covering areas such as floorplan development, power, cooling, rack layout, networking/server installation, configuration of high performance servers including graphical processing units (GPUs) for massive computational parallelism, and construction of custom storage area networks (SANs). We configure and maintain networking devices, security appliances, security information and event management (SIEM). Also, we operate hypervisors such as VMware vSphere and ESX/ESCi, KVM, Microsoft Hyper-V, and Xen Server. We can install operating systems either on bare hardware (e.g., for high performance or scientific computing) or on virtualized servers. We stress automation, through popular tools such as Vagrant, Puppet, Ansible, Chef, etc.

We have set up, managed, and operated a variety of cloud and big data software configurations such as CloudStack, CloudBase, OpenStack, Xen Cloud Platform, and Hadoop, as well as specialized cloud configurations for Defense customers such as the Distributed Common Ground System – Army (DCGS) Edge Node (DEN), Tactical Cloud Reference Implementation (TCRI), and Naval Tactical Cloud (NTC). We have operational experience with most major big data technologies such as the Lambda Architecture, Spark, Storm, NoSQL databases (e.g., Accumulo, MongoDB, CouchDB), massive data ingestion via frameworks such as Kafka, massively scalable indexing (e.g., via Druid) and searching (e.g., via ElasticSearch).

We have also supported a wide variety of middleware, including most major databases (see Enterprise Data Warehouses/Large Data Analytics ), enterprise SharePoint farms, application servers (e.g., JBoss, WebLogic, WebSphere). We support Windows Server through 2016 beta and many variants of Linux including Red Hat Enterprise Linux. We are experts in applying STIGs (Security Technical Implementation Guidelines). The infrastructure and middleware we configure is normally set up to support DevOps (see DevOps/Test Automation ), using containers for portability of code, and scalability via Kubernetes.

The extensive knowledge from our in-house use of the infrastructure and technologies above gives Harmonia an unusually deep understanding of how to architect and implement cloud deployments for our customers who want to reduce the headaches of operating on-premises data centers. On the development side, we can transform customer development environments to RedHat OpenShift. For production environments, our staff is experienced in architecting deployments to SharePoint Online in Office 365 as well as Azure and Amazon Web Services. We apply carefully vetted methodologies to plan enterprise services cloud migrations of on-premises server decommissioning in carefully executed waves that ensure uninterrupted service to enterprise users.
