OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface. 

 OpenStack Compute (Nova): Manages large networks of virtual machines. It is designed to manage and automate pools of compute resources and can work with widely available virtualization technologies, as well as bare metal and high-performance computing (HPC) configurations. 

 OpenStack Storage (Swift): Object and Block storage for use with servers and applications. Object Storage is ideal for cost effective, scale-out storage. It provides a fully distributed, API-accessible storage platform that can be integrated directly into applications or used for backup, archiving and data retention. 

 OpenStack Networking: Pluggable, scalable, API-driven network and IP management. Like other aspects of the cloud operating system, it can be used by administrators and users to increase the value of existing datacenter assets. 
 
 OpenStack Image Service (Glance): Provides discovery, registration, and delivery services for virtual disk images.

OpenStack - Software for building Private and Public Clouds

OpenNebula provides solution for building and managing virtualized enterprise data centers and cloud infrastructures to enable on-premise IaaS clouds. OpenNebula interoperability makes cloud an evolution by leveraging existing IT assets, protecting your investments, and avoiding vendor lock-in. penNebula was designed to address the requirements of business use cases from leading companies and across multiple industries, such as Hosting, Telecom, eGovernment, Utility Computing and lot more. 
 OpenNebula can be primarily used as a virtualization tool to manage your virtualized infrastructure in the data center or cluster, which is usually referred as Private Cloud. OpenNebula supports Hybrid Cloud to combine local infrastructure with public cloud-based infrastructure, enabling highly scalable hosting environments. OpenNebula also supports Public Clouds by providing Cloud interfaces to expose its functionality for virtual machine, storage and network management. 
 OpenNebula orchestrates your existing storage, networking, virtualization, monitoring, and security platforms to enable the dynamic placement of multi-tier services.

OpenNebula - Data Center Management Solution

Scalr is a pretty darn good open source cloud management tool. It provides both an automation framework and a web interface (where is this volume mounted) for managing infrastructure on the cloud, like EC2 and GCE. It supports multi-cloud and it is integrated into Opscode Chef, for configuration management.

Scalr - Cloud Management Software

Kubernetes has made it very easy to deploy applications to the cloud at a higher scale than ever, but the development practices have not evolved at the same speed as application deployment patterns. Today, most developers try to either run parts of the infrastructure locally, or just test these integrations directly in the cluster via CI jobs or the "docker build, docker push, kubectl apply" cycle. It works, but this workflow is painful and incredibly slow.

Okteto - A Tool for Cloud Native Developers

Dasein Cloud (pronounced "da z-eye-n") is a Java-based cloud abstraction layer that enables programmers to build applications under a "write-once, run against any cloud" philosophy. It provides an abstract model under which most IaaS and some PaaS services can be modeled. Developers write applications to the Dasein Cloud model and it is then translated into the underlying cloud provider model.
