Modern day networks have to have additional dynamic variations than common networks, and the option to constructing these dynamic abilities is community automation, which usually means the job of network engineers is modifying.

Traditionally, community reconfigurations essential guide work that may involve network downtime whilst modifications ended up built. Community automation has the likely to mitigate this downtime by re-routing network site visitors or scheduling the downtime for off-peak hours.

To meet up with the problems of this transform, traditionally trained network engineers could gain from certifications in automation. Engineers require approaches to reduce the time-consuming, mistake-susceptible handbook alterations that at any time-changing workloads desire.

Cisco and Juniper Networks offer certs certain to automation, and people are described in this write-up. Other suppliers, like VMWare, AWS, and Microsoft Azure, have certifications that validate carefully relevant techniques.

Enterprises search for network automation skills

The very first important use case for network automation is DevOps workflows. Given the highly dynamic mother nature of the modern day application stack there are scenarios wherever changing the underlying community for scalability or availability provides price to the software-web hosting architecture.

Next, multi-site company networks ordinarily use WAN connections and web page-to-website VPNs to establish cohesive networks. This design can be increased by leveraging program-defined WAN (SD-WAN), which can dynamically switch among the WAN connections, optimizing the alternative based on link speed, expense, and reliability.

Third, with community components forming a vital component of company infrastructure, technique updates and configuration modifications can suggest scheduling downtime. Network automation has the possible to mitigate downtime by re-routing targeted visitors around devices getting up-to-date or scheduling downtime for off-peak hours.

Technologies this sort of as containerization and virtualized workloads are escalating, and the dynamic nature of the application service stack benefits from a network that is similarly dynamic. Additionally, info facilities that host multi-tenant or hybrid workloads may possibly have market or safety prerequisites for separating facts belonging to unique clients or even branches within just the similar firm. The resolution to creating these dynamic capabilities is network automation.

What are community-automation competencies?

New abilities that network engineers want to meet the troubles of network automation involve the means to develop policies and rule sets that can carry out configuration adjustments on the fly. These insurance policies can affect VLANs, subnets, and routing, amongst other aspects. The occupation of automation engineer must just take into account that when main ideas and protocols nonetheless pertain, aspects of equally the components and the automation method are extremely seller precise.

That reported, there are some commonalities amid these devices. Most network automation platforms contain building out guidelines which generate configuration changes primarily based on certain circumstances being fulfilled. This necessitates community automation engineers to realize infrastructure-as-code concepts as perfectly as popular information formats like JSON, XML, and YAML.

Scripting skills, notably applying Python, can also be very practical in equally planning automation procedures and in tests them to guarantee consistency and reliability. A business grasp of application programming interfaces (API) is also beneficial considering the fact that lots of automation platforms count on them for integration concerning various devices.

Cisco gives DevNet automation schooling

Cisco’s DevNet certification keep track of is built up of affiliate, expert, and specialist-amount certifications. Candidates are needed to exhibit proficiency in advancement capabilities these kinds of as information structures, style patterns, and aspects of edition control. They will also be expected to find out how to interact with programs as a result of APIs, webhooks, and HTTP conversation.

Cisco expects candidates to grow to be proficient with Cisco SDKs, managing Cisco platforms as a result of APIs, and comprehension resources Cisco will make available as a result of its DevNet developer group. Organization subjects encompassing application deployment and security are also essential worries for business-amount certifications, opening a large selection of topics like containers, virtualization, unit tests, protection of techniques, encryption, firewalls, and vulnerability dealing with.

Candidates will have to have to clearly show automation skills, in particular workflows, infrastructure as code, and common automation platforms like Ansible, Puppet, Chef, and Cisco NSO. Successful the Cisco certification involves a mastery of networking fundamentals these types of as MAC addresses, VLANs, IP addresses, routes, subnets, switches, routers, firewalls, load balancers, and NAT, amid myriad other topics necessary to being familiar with modern-day networks.

The Cisco DevNet Affiliate certification needs candidates to move the 200-901 DEVASC examination. Cisco delivers a self-paced instruction class for it called Building Purposes and Automating Workflows applying Cisco Platforms. It expenses $800. The DevNet Experienced and Specialist certifications equally need the 350-901 DEVCOR cert as their foundation. The self-paced prep course for the 350-901 DEVCOR exam is identified as Producing Apps using Cisco Core Platforms and APIs, also $800. DevNet Skilled candidates have to also go one particular of 8 focus exams, all of which are targeted on automation or growth of a variety of Cisco platforms. The Specialist degree DevNet cert calls for completion of an 8-hour lab exam, which requires candidates to navigate the total progress lifecycle from design via development to deployment and maintenance.

Juniper problems affiliate and professional certs in automation

Juniper Networks’ DevOps certification monitor delivers associate and specialist certs: Juniper Network Qualified Associate, Automation and DevOps (JNCIA-DevOps) and Juniper Community Qualified Specialist, Automation and DevOps (JNCIS-DevOps). Every has its very own certification test, and the specialist cert needs the affiliate-amount certification as a prerequisite. Juniper certifications are legitimate for 3 several years and can be recertified via additional examinations or system attendance.

Juniper test objectives aren’t as challenging as what Cisco’s, although at a high amount they are quite comparable. Subjects surrounding the Junos automation stack as well as standard DevOps principles make up the initial set of aims, with operation and use of NETCONF, XML ideas (including XPath), and API utilization building up the next.

Data serialization and templating are also main targets, incorporating matters this sort of as YAML, JSON, Jinja2, and XML. Python is a different space of emphasis, and candidates ought to present proficiency in the Junos Snapshot Administrator (JSNAPy), Jinja2, Distant Course of action Phone calls, exception dealing with with PyEZ, and handling machine standing and configuration. Candidates should really also be common with Rest APIs in standard, and a lot more especially with the Junos Rest API choices, which include the Junos Rest API Explorer and Customer URL obtain. Candidates for the expert-stage certification will also want to be familiar with automation principles (participate in books, Tower, and applying SALT to automate Junos), Junos automation scripts (commits, functions, translation, SNMP scripts, and SLAX), and YANG versions.

Major automation engineers get paid $200,000-plus

The techniques a community automation engineer span both deeply technical regions of business networking and application development. Thanks to the degree of specialization in the contemporary IT workforce, it is uncommon for an specific to attain pro-level specialization in both disciplines. That suggests it’s a position-seekers current market for men and women with proficiency in the two regions that they obtained possibly by way of task encounter or applicable certifications. These work opportunities will mostly be accessible at huge enterprises, government corporations, or consulting firms that offer products and services to enterprises.

Salaries for community automation engineers frequently start out in between $90,000 and $110,000 for positions that call for just one to 3 a long time of expertise. Candidates with more than five many years of experience can hope to generate $125,000 to $175,000, while all those with both of those encounter and certifications have a leg up landing work opportunities paying out up to $215,000.

Observe: Numerous community automation positions are a very good suit for remote operate. Considering the fact that most of the effort and hard work is put in on layout, improvement, and screening, there is minimal have to have for on-site get the job done. In numerous instances network automation projects span numerous physical destinations in any case, including additional justification for operating from house.

So for job improvement, better fork out, and being pertinent as networks evolve, teaching in network automation abilities could be just what you have to have.
