€6-12 EUR / hour

We need you to start working immediately on 2 projects (one our own, one our customer's). You will be working next to our lead backend developer who has set up the existing environment and has some experience in system administration. You need to be good at: - Linux/Unix and Docker (containers in general). - Shell scripting - Networking engineering, including DNS, firewalls, load balancers - Fast learner, fast worker and always the fancy latest technology - Good spoken/written English - Working under the pressure Job description We do have our own Ubuntu server in MSI GT72S 6QE Dominator Pro laptop (i7-6820HK, 16GB RAM, 250GB SSD for apps + 1TB external for storage). We have installed there Nginx, PHP and MySQL. We want to install there immediately these apps: our own custom built Laravel/Apiato/VueJS based ATS system, InvoiceNinja, GitLab, Jenkins, PMD and in future many more. We use it also for our customers as a development server. As we do use some of our own apps in this server also as a production environment then we need to be secure if something happens with that laptop (burns down, internet goes down, whatever) so we do have another laptop in different location Dell Inspiron 17R 5720-8643 (i5-3210M, 8GB RAM, 250GB SSD + 1TB external) that we want to sync with the one we have so in case the main laptop isn’t reachable the slower one can serve while we fix the main laptop. As the backup one is less powerful we can keep some apps not running on it (PMD, customer dev environments?). We do use [login to view URL] to point the domain names to the correct IP as the IP on the servers’ locations might change each time the router is restarted. So you need to suggest the best options to achieve our goal and then do the job: 1. Should we use virtualisation so that different apps work on different VPS? How much memory will that eat? 2. Should we use Docker or any other container for easier sync? What advantages Docker will give? How much memory will that eat? How much extra work or saving working time will that give? 3. Suggestions what else to do welcome. Is it ok at all to have the backup server that much weaker? Is it ok at all to have laptops as servers? That will be your first job to quote and discuss first. Later you’ll need to also work on potential virtualization, better organization of multiple apps, how to optimise apps and the whole system for eating fewer resources and work faster, security etc. Also, work on our customers' projects, etc.

I love deploying servers! I have done most of what was asked before and it sounds great! I use ddns with my home computer that runs Jenkins, Nexus, BitBucket ( similar to gitlab ) , nginx, and a few other things you mentioned. I would be available 12/7 specifically for your project and I will have the ability to answer any given question. You should probably not use virtualization if you do not need to cause you will have to run multiple operating systems and the ram consumption adds up. Docker is like virtual machines but for one service therefore using little amount of ram and easy to [login to view URL] servers do not need to be powerful, they just need a fair amount of storage. Please message me immediately if your are interested!!!

You are looking for a DR type of setup, I have done many enterprise level DR's ad DR solutions. There are multiple ways to replicate data. Do yo want to replicate on Dell Inspiron 17R 5720-8643 to the external Drive?? How far two systems apart to consider replication. One method is to do rsync, another is to use block level replication using DRBD. I)Virtualization and how much RAM would be needed depends on more information related to application you are running and what would be the peak traffic, capacity planning. II)Docker can be the great choice, again depends on more information related to app. III)Yes, I have a good expreience with all type of servers, even hosted some laptops in past, let's discuss in detail? message me.

Hi, I have read your proposal and your requirement. My experiences to take part in some projects are follows. 1. OpenStack customization for the certain company. 2. OKD(OpenShift, Kubernets, Docker) project and all I had to is to make s2i docker image and CI/CD using Jenkins on k8s 3. Network Device developing project(making IPSec VPN). 4. I am really workaholic. My suggestions about your questions are follows. 1. You have to use virtualization of the different app work on different VPS. You have to keep high-availablity in your service, so the clients don't know whether the server goes down or not. In this respect, I think you have to use virtualization of the different apps on different ones. 2. You can use Doker. The best advantage of the docker is really lightweight and easy to use. If you build CI/CD using Jenkins, you can keep the syncronization between Prodution and Development. According to my experiences with OpenShift, it's really helpful for operators. 3. For high-availablity, for example, preventing from disaster or the error of service itself, you have to build backup system and HA. You can implement HA by using Nginx, or haproxy tools. If you use MySQL database, you can use mysql-galera plugin for replication.(ha, fault-tolerent) But according to my experiences, it costs. I mean such system needs many hardware resources. This is what I want to sgguest you in a simple word. if you have an interested in my knowledge or experiences, please be in touch.
