Modern Application ArchitectureToday, cloud is becoming the de-facto platform to deploy and scale applications. Businesses are writing new applications to run on a cloud platform and handle software and hardware failures in the application layer.

The adoption of cloud native application architecture has gathered tremendous momentum in recent years. Cloud native applications di�er from classical 3-tier applications in several ways:

• Cloud native applications must be able to scale massively and dynamically on demand.

• Each layer (or component) within the application is considered a service (referred to as microservices).

• HA model of a cloud native application di�ers from classical applications in that it each microservice comprises of many individual component processes, that are usually stateless and hence created and destroyed dynamically without any impact to the overall application.

• The application must be able to function with minimal human intervention. Applications, provision and con�gure the infrastructure they need programmatically at run time.

• This approach is often referred to as infrastructure as code.

A simple multi-tier application that consists of the following layers:• A SQL (such as MySQL) and NoSQL (such as Cassandra) database where a

persistent state resides• An application services tier that contains the core business logic could be

built in Java, Python or GoLang• A cache tier to reduce response time could be Redis Cluster• A web tier that contains the front-end code built on HTML (such as NginX or

Apache), CSS, JavaScript (such as using Node.js, Express, and Angular.JS) and client-side utilities

Each of these layers in the stack can have multiple instances depending on the scalability needs of the application.

The ZeroStack SolutionThe ZeroStack Intelligent Cloud Platform is designed with cloud native applications as a �rst class use case.

Convert Bare-metal server to a highly reliable cloud in minutesThe ZerosStack Cloud Operating System (Z-COS) self-healing, highly distributed on-premise control plane. It can run on existing servers or can be procured from ZeroStack as Z-Blocks Hyper-Converged Hardware Cloud Building Blocks which come preloaded with the latest version of Z-COS.

It has a full-functioning, built-in highly optimized and high performing version of KVM hypervisor. It contains distributed control plane that allows seamless and dynamic addition and removal of servers in the cloud cluster that allows clustering and pooling of compute, memory and IO resources. This implements reliable, always-on control plane layer that is symmetric and self-healing. It also o�ers a distributed, scale-out storage solution (block and S3 Object) with four di�erent storage classes: SSD, HDD, SSD with Replication, and HDD with Replication. A Software De�ned Networking layer o�ers performance and reliability at cloud scale by providing network overlays and segmentation. The solution implements distributed virtual router (DVR) mode with Open vSwitch that provides services like simple point-and-click internetworking, built-in �rewalls, and load balancers.

It has out-of-the-box support for AD/LDAP and popular orchestration frameworks like Puppet, Chef, and Ansible.

Rich API SupportThe ZeroStack Intelligent Cloud Platform exposes a 100% RESTful OpenStack API for all of the important infrastructure services. Being open, these APIs have popular bindings in Java, Python, and other languages.

These APIs are available for the following important infrastructure services: • Compute API: Create VMs with the accurate �avor from the correct image

and place it on the correct physical server.• Block Storage API: Create volumes of the correct pool type, thus enabling

the optimal performance needed by your application components.• Network APIs: Create private networks to isolate application layers or

create routers to connect one layer to another.• Security APIs: Create security groups to expose application-speci�c ports

and protocols. Generate upload key-pairs for secure password-less access to workloads.

• LBaaS APIs: Create software-de�ned load balancers to front application services for a scale-out deployment.

• Object Store API: Create buckets, and upload and read objects as needed by an application.

• Application Template Support: The templating API has a YAML format that can be used to de�ne a complex multi-tier application with ease.

• Identity, Access Control, and Session Management API: Enable proper role-based authentication, session management, authorization, multi-tenancy.

The API set enables you to programmatically and dynamically recon�gure the application development environment based on your needs. Popular orchestration frameworks like Chef, Puppet, Ansible, and SaltStack leverage these APIs as well.

Map your organization. Scale rapidly.The ZeroStack Intelligent Cloud Platform can be organized into business units (BUs). These business units’ map to departments within your organization. Projects can be created within each business unit. Each project acts as a workspace and can be allocated to a team. BUs and projects enable self-service and eliminate the old ticketing-based processes where users endure multiple tickets to create VMs. With the ZeroStack Intelligent Cloud Platform, users can leverage a complete set of RESTful APIs and programmatically create resources within their projects.

Deploy Applications RapidlyThe ZeroStack Z-Brain SaaS portal o�ers the Z-AppStore, an app store with built-in images and application templates. Users can further customize this app store based on their speci�c requirements. The Z-AppStore o�ers various SQL and NoSQL templates that allow end users to create a stateful microservices.

In addition, Z-AppStore o�ers a list of prepackaged OS images and application stacks that developers can use to deploy instances of application instantly. The zAppStore also o�ers a mechanism to de�ne application templates based on OpenStack Heat.

These templates make it very simple to de�ne an entire application stack orindividual layers of an application.

Applications can create a single-node MySQL instance for test deployment or multi-node MySQL cluster for production with equal ease.
