Organizations from many industries have started moving their IT infrastructure to the cloud faster than ever.

When we mention infrastructure, it’s not just server, database, storage – there's more thereto .

A typical medium to an outsized organization would have the subsequent infrastructure components.


Load balancer




Security/DDoS protection

and Firewall

In a traditional infrastructure, Firewall appliances may cost around a couple of thousand dollars and wish a firewall admin to manage it. It’s expensive.

Thanks to the managed firewall where you don’t need to buy expensive hardware appliances and hire an administrator for them.

The managed firewall may be a service where you buy what you employ either on-demand or monthly. You don’t need to worry about the hardware. you'll administer the firewall rules from intuitive GUI or command lines.

Note: the subsequent are infrastructure firewall and to not confuse with the online Application Firewall.

Let’s take a glance at a number of the managed firewall you'll use to guard your production infrastructure environment.

Google Cloud Platform

Google Cloud creates default firewall rules for every VPC (Virtual Private Cloud) network. you'll allow or deny connections to ingress (incoming) or egress (outgoing) rules, and that they are effective immediately.

It supports priority order between 0 to 65535, where rock bottom rule number got the very best priority. All are managed either through the “Firewall rules” section under VPC Network or instruction.

I use GCP and love simplicity.

Source support multiple options like IP ranges, sub-networks, source tag, or service accounts, and during a single line, you'll give multiple port numbers.

If you're already using Google Cloud, then fiddle with firewall rules to explore the chances to harden and secure the server at the network firewall level.

Check Point

A known name within the security industry – Checkpoint got the vSEC product for public and personal cloud security. vSEC is out there on a public cloud like AWS, GCP, Azure & VMware, and personal cloud as OpenStack, VMware NSX & Cisco ACI.vSEC provides advanced threat protection including firewall, IPS (Intrusion Prevention System), Anti-virus, Anti-bot, Zero-day protection, DLP (Data Loss Prevention), and application control.

You can try a FREE test drive.


Barracuda NexGen firewall is out there on the general public cloud – AWS, GCP & Azure. NexGen may be a full-featured firewall solution to supply network-level protection. It acts as a network gateway between your network and therefore the Internet and inspects all inbound & outbound traffics to guard supported the policies.

NexGen firewall got a built-in SD-WAN (Software-defined wide area network) to supply connectivity between the cloud to an on-premise data center.


Zscaler Cloud Firewall is powered by patented technologies like SSMA, ByteScan, PageRisk, Nanolog, PolicyNow to supply advanced security protection.

You can create a granular level of policies to regulate protocol, ports, location, user department, etc.

In my previous post, I talked about the way to implement SSL certificates on shared hosting, Cloud/VPS server, Cloudflare, etc., and a few of you asked the way to roll in the hay on Load Balancer (LB).

It’s an honest idea to terminate the SSL handshake at a network edge device for several reasons.

It’s faster

You can make changes on the fly

Easy maintenance

SSL/TLS hardening managed by LB

Google Cloud Platform (GCP) is astounding, and that I use it for Geek Flare and just like it. GCP offers many cloud solutions including the load balancer.

There are three sorts of load balancers available, and if you're hosting Web-based applications, then the HTTP(S) type is suggested.

I assume you have already got the subsequent ready.

If you're performing on a multi-server application environment where you've got a requirement to share a filing system between multiple servers, then you bought to line up NFS (Network File System).

NFS allows you to share the filing system on quite one server, but implementation requires some administration skills.

In a traditional infrastructure environment, you'll need to involve multiple teams, and would take time to make NFS. But if you're using AWS, you'll catch on wiped out a couple of minutes with their EFS (Elastic File System) service.

lets you create scalable file storage to be used on EC2. You don’t need to bother about capacity forecasting because it can proportion or down on-demand.

A quick illustration was taken from the AWS page to offer you a thought of how it works. Some of the EFS advantages are:

Fully managed by AWS.

Low cost, buy what you employ.

High available & durable

Automatically proportion or down.

Scalable performance

I’ve two EC2 Ubuntu instances running, and during this tutorial, I’ll create one EFS then mount it on both EC2 servers.

Let’s catch on started.

Login to AWS console

Go to Services and choose EFS under storage (direct link)

Click “Create a filing system .”This concludes you’ve created EFS and prepared it to be mounted on EC2 instances.

Mounting EFS on EC2

Before mounting, you would like to put in the NFS client. If you expand the list and click on “Amazon EC2 mount instructions”, you'll get the small print.

This is easy, isn’t it?

I tried creating a few files, and the overall performance looks good. cloud technology companies AWS EFS looks promising, and if you're in need of filing system sharing across EC2 instances, then provides a try, and that I am sure you'll love it.

You don’t need to bother about backup if you're hosting your website on shared hosting as most of the hosting provider takes care of the backup for you.

However, once you migrate hosting to cloud-like Google Cloud or AWS, then there are few things that you simply need to look out for yourself.

Backup is one among them!

Lately, I moved Geekflare to Google Cloud Platform and was trying to find a one-click backup option, but unfortunately, it doesn’t exist.

After some research, I learned backup procedure is slightly different, and that I loved it. the great thing is, you've got full control over your backup.

There are multiple levels (application, configuration, logs, etc.) of backup, and therefore the following I will be able to mention taking complete VM backup manually and automatically.

The term wont to take a backup of Google Cloud is named “snapshot.”

Some of the benefits of a snapshot.

You can take a snapshot while a disk is attached to the instance – no downtime during backup

It’s differential rather than creating full disk backup whenever – it reduces the backup storage cost and fast operation

Manually using Google Cloud Console

Google cloud console has the choice to require a snapshot of the disk, and it's easy.

Log in to Google Cloud and attend Disks under Compute Engine

Click on the disk name which is attached to the instance, and you would like to require a snapshot


This indicates VM disk backup is completed. Whenever needed, you'll use this snapshot to restore/create a replacement VM with an equivalent state at the time of VM backup.

Automatically using Scripts

If your application has frequent changes and would really like to automate taking a snapshot regularly then the subsequent will assist you.

Log in to the instance in which you would like to require auto backup

Create a folder where you would like to store the script file

Download the script file by default, a script will keep the snapshot for the last seven days. If you would like to vary this schedule, then edit the script file and alter the worth of OLDER_THAN=7

Automatically using Google Cloud Console

Google recently introduced these features, and that I like it. Now, GCP has the choice for you to schedule a disk snapshot from the console itself.

Go to Compute Engine >> Snapshots

Click on the Snapshot schedules tab and therefore the following popup will appear. Click Create snapshot schedules

Let’s explore a number of available options.

Region – select where you would like to store your VM snapshot (backup)

Schedule frequency – choose how often you would like to require a backup from daily, weekly, hourly

Start time – at what time backup should be made. Choose low peak hours.

Autodelete snapshots after – what percentage of last snapshots you would like to stay at any time.

Deletion rule – what should happen if you delete the source disk (VM)

Once created, you ought to see them listed. That’s all!

Google Cloud will take the snapshot supported by the schedule.

You see, just spending a couple of minutes to line up a backup is often a lifesaver. information technology colleges On top of the snapshot, you ought to also consider enabling screenshots which may help to understand the VM state.
