You can use this guide to help you when you design an Anthos architecture, whether in Google Cloud, multi-cloud or in hybrid cloud environments. It is intended to highlight the dierent concepts and components that you must consider when you implement Anthos. To get maximum value from this guide, you should already be familiar with basic Anthos concepts, as outlined in the Anthos technical overview. You should also be familiar with basic Kubernetes concepts such as clusters. For more information, see Kubernetes basics and the Google Kubernetes Engine (GKE) documentation The guide focuses on the following aspects of Anthos design: ● Personas ● Anthos architecture model ● Networking ● Cluster architecture ● Identity management ● Security and policy management ● Services ● Persistence and state management ● Databases ● Observability Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 3.0 License, and code samples are licensed under the Apache 2.0 License. For details, see our Site Policies. Oracle and Java are registered trademarks of Oracle and/or its affiliates. 4 Anthos architecture foundations and principles Personas There are a number of personas that interact with the Anthos plaorm. The purpose of this section is to describe the roles and responsibility of each persona, and how and in which capacity they inteace with Anthos. Anthos users tend to be split into application and plaorm teams, and within these teams there are two primary personas, Administrators and Developers. These personas have similar tasks and responsibilities, but oen dier in terms of the systems they manage, the end users they serve, and the technologies they use. The following six personas are impoant when considering Anthos: 1. Application owners and developers 2. Plaorm administrators and developers 3. Security administrators 4. Site Reliability Engineers (SRE) and operations 5. Network administrators 6. Storage and database administrators It is impoant to note that these personas represent job functions, not people. This means in dierent sized and shaped companies, the same person might assume multiple personas. Identifying and understanding each persona is helpful when determining a comprehensive architectural design.

This group owns the application’s roadmap and the source code, including bug xes, peormance regressions, and incidents. Application developers need a plaorm to be able to build, test and reliably release soware to their customers. Anthos plaorm admins (persona discussed below) ensure this functionality exists in the plaorm for the application owners. Company Size - Typically, this persona exists in organizations of all sizes. Skills - Product management (PM) and soware development and engineering (SWE) Inteace to Anthos - This persona typically inteaces with Anthos through Git. Application owners and developers do not need to fully understand the underlying plaorm, so long as it meets their need for soware development and delivery. Git provides an abstraction layer between individual Anthos plaorm components and Application owners. Using GitOps workows, such as feature branches, pull/merge requests (PR/MR) in conjunction with continuous integration and continuous delivery (CI/CD) workows, application owners can build, test and deploy applications reliably and safely to the Anthos plaorm without dealing with the underlying complexity of individual Anthos components. This allows application owners to continually build and deliver soware, while plaorm admins manage the life cycle of the Anthos plaorm without strong co-dependency on one another. Application administrators and operators Function - This persona is responsible for operating live production deployments, monitoring their health, and rolling out updates as needed. Their chaer includes monitoring, capacity planning, deploy/rollouts, incident response, troubleshooting, automation, and scaling. They are ultimately responsible for maintaining the Service Level Objectives (SLOs) of a paicular application or service. This group is responsible for designing and implementing CI/CD pipelines as well as monitoring systems to observe the peormance and functionality of the application. It is impoant to note that this group operates at the application/service layer. Anthos components and their management is the responsibility of plaorm administrators. Plaorm administrators work with Google Cloud Suppo for Anthos specic issues, while SRE/Ops work with both the application owners and plaorm administrators to ensure applications are kept within the required SLO. Company Size - Almost all cloud organizations, as well as medium to large enterprises.

Inteace to Anthos - Git and CI/CD pipelines to Anthos, observability system, Google Cloud APIs, Google Cloud Suppo Plaorm administrators and developers Includes Plaorm Security, Network, Storage, and Database administrators Function - This persona

  • Solarwinds IP Address Manager ELIMINATE IP CONFLICTS and SAVE TIME MANAGING DHCP, DNS, and IP ADDRESSES
    SolarWinds IP Address Manager ELIMINATE IP CONFLICTS AND SAVE TIME MANAGING DHCP, DNS, AND IP ADDRESSES DOWNLOAD FREE TRIAL Fully Functional For 30 Days Networks are getting bigger and more complex, driven by the need for greater performance, BYOD, server virtualization, cloud migration, and smart devices. Meeting these challenges begins with managing your inventory of IP addresses and vital DHCP and DNS resources. SolarWinds® IP Address Manager (IPAM) provides you with centralized IP address management that works hand-in-hand with unified DHCP and DNS administration. This means that teams can quickly find available addresses and easily configure them on virtually any DHCP and DNS system. IPAM also alerts you in advance of serious problems like address conflicts, poor performing DHCP/DNS servers, or full DHCP scopes. IP Address Manager at a Glance • Prevent IP conflicts with powerful IPv4 and IPv6 address management • Save time provisioning or reclaiming IP addresses with seamless DHCP and DNS integration • Avoid problems by monitoring and receiving alerts on critical IP events • Delegate IP administration to network and system admins using role-based access • Integrates with SolarWinds Network Performance Monitor (NPM) and Server & Application Monitor (SAM) Features IPv4 and IPv6 Address Management IPAM actively identifies and manages IPv4 and IPv6 addresses and uses active scanning to discover and track subnets and associated address blocks. Finding an available address is as simple as navigating to a target subnet, viewing, and selecting an available IP address. Also, view transient IP addresses to easily identify orphaned IP addresses and reclaim them. Integrated DHCP and DNS Configuration Management IPAM works with your multi-vendor DHCP and DNS services—no additional proprietary software or hardware is required for management.

Documentation Basics, such as documenting your switches... – What is each port connected to? – Can be simple text file with one line for every port in a switch: • health-switch1, port 1, Room 29 – Director’s office • health-switch1, port 2, Room 43 – Receptionist • health-switch1, port 3, Room 100 – Classroom • health-switch1, port 4, Room 105 – Professors Office • ….. • health-switch1, port 25, uplink to health-backbone – This information might be available to your network staff, help desk staff, via a wiki, software interface, etc. – Remember to label your ports! Documentation Maybe this process should be automatic. Tools to help automate network documentation are something to consider. – You can write local scripts (programs) to do this. – Consider among several automated documenation systems for networks. – You’ll probably end up using and doing both.
