Unfortunately Dropbox quits syncing when you log off. Has anyone come up with a solution that keeps Dropbox running and syncing even when logged off the computer? I am trying to use it for server backup storage and not syncing when logged off will be a show stopper.

HTML5 and CSS3 Fundamentals

Build a website from the ground up by first learning the fundamentals of HTML5 and CSS3, the two popular programming languages used to present content online. HTML deals with fonts, colors, graphics, and hyperlinks, while CSS describes how HTML elements are to be displayed.

We noticed that we can't open a remote console for a deployed VM from VRA web interface, we get the below error:

"Cannot connect to remote console. Verify that the machine is powered on and connected to the network."

The VMs are powered On, on Vcenter side the VMs look healthy.

This is what i have tried so far:

Ping from Host to vcenter where the VRA VM resides:

What are the security & compliance requirements we can safely
demand/expect from Oracle ERP (Enterprise Resrc Planng) Cloud.

Likely Finance, HR, Procurement modules will be used in this
cloud ERP.

a) Data sovereignty: DC must be local?

b) BCP/DR drills done yearly with DR centre also hosted locally?

c) this is an SaaS?  So we can apply all  the SaaS compliance
    requirements on them including returning data to us &
    secure erasure of data when exiting?

d) ... any other ... ?
Hi Experts,

We have a client whose machines are in workgroup mode so no AD or any on premise infrastructure. We are looking to add them to Azure AD since they already have E3 licenses and are using Office 365. My questions are:

1. Will their logins change on their machines? i.e. currently they sign in as somerandomname, will their computer login change to for their computer? I am just thinking if we will need to do a profile migration to preserve all their settings?

2. What Office 365 licenses are needed to achieve this? They have E3 and are on Windows 10 Pro. Do they need Windows 10 Enterprise to join Azure AD?

Thanks in advance
I am looking for the best DB giving the following considerations.

1)  I will be deploying a .net /angular application into Azure via Docker / Kubernetes.

2)  I would want on prem and cloud capabilities..natively

3)  Finally we will be moving to AWS in the next migration is important as well.

I will want to use relational database.  High availability, on prem and off prem  capabilities, as well as other great scaling capabilities.

Also having a hard time with the cost model any knowledge there would be helpful.

I will be doing this in a CI/CD ...I am guessing I would have docker in my local enviornment (free)  then move to a dev / stage/ prod enviornment.

I've briefly looked into Encryption with Azure VMs and see there are a few options.
Can anyone suggest their experiences with it and whether they used native azure or something like cloud link?

Hi Experts,
 We are working on publishing some app through VM and with Web App. We are trying with both options.

We would like to compare and check which option is not expensive or which option is best?

Can you please help us to investigate difference?
we are reviewing our data leakage controls and there is a point in policy regarding uploading company data to 'cloud storage; (e.g. forbidden). There are tight controls on USB/DVD/Email etc, but I was wondering:
1) what the common/free cloud storage solutions are in 2019, and..
2) as a company from a policy enforcement perspective, is it as simple as blocking access to those cloud storage websites via your web filter/proxy to enforce this, or is it a bit more complicated than that. And if there is more to it, what other types of controls need to be in operation.
Hi Experts,
 I am new on Microsoft Azure. We are working on Proof of Concept for IaaS and Paas.  We have received the architecture diagram and based on that we have created the 38 resources (Vnet, subnet, VM, Load balance etc) for Region 1. Now we have to create same resources for Region 2. ( Diagram attached).

Can you please suggest and provide detail solution for create those resources automatically?

Is it possible to get script for whole diagram?

Let me know if you need any clarification.

Please Advice.
Looking for suggestions for a good DB to use given the archictecture of this application.

I have been given a pretty open ended choice to make so looking for reasons to use on dB over another.

Here is the environment:

I will be developing a web application using .net core.
I will be building a parallel deployment ..
1)  Traditional Azure deployment.  
2)  I will be using Docker in the was hoping to put that planning in at the beginning of my design...but this initial rollout will just be using Azure in the private cloud.
3)  I will have some level of web api and what extent I am not sure.
4) My front end so far I am leaning the latest Angular 7.

My company wants me to pilot something new so that rules out SQL Server versions or Oracle.

I am gussing this leaves me to Mysql or MariaDB.  PostGresSQl


some version of NoSQL such as Mongo or Cassandra.

This application will be low transactional...and will not be very large..thus the reason the company wants to use it to pilot...yet
at the same time I dont want to put that in as the requirement as its possible this is more a pilot for the company to think about one database going forward
versus having many different versions of Dbs in the enterprise.

Currently we have alot of SQL Server, Oracle, and DB2.  I also believe out external website is Maria.

So any thoughts?

I honestly hate just picking one only to say lets test it.  But that does seem to be the …

We are calling a tender for Managed SOC & drafting requirements.
Can point me to samples or share requirements normally expected
of vendors for such Managed SOC?

Besides piping firewalls, network devices, servers, UEBA events to
them for correlation, is it common to pipe  originating IP addresses
of incoming emails (eg: O365) to them to check against blacklists?
I felt O365 antispam & antiphish & anti-malware protection is
not enough.

We have EDR in place but was told to do MDR (Managed Detection
& Response), we must go back to the same EDR vendor (Trendmicro
to be specific) but TM doesn't do managed SOC, only MDR.
We don't want fragmented service providers ie one for managed
SOC & another for MDR.

Also, can we include a requirement  such that we do away with our
current Defacement vendor (it's a Telco) & the managed SOC use
their own tool to manage our URLs  (eg: using 'wget' or 'curl' to
download our web pages contents & compare against a baseline?
Or this is a function specific to Defacement vendor only & SOC
doesn't normally do this function?

What are the certifications required of such vendors eg: ISO27001/2,
must have certain encryptions, ... ?  

I guess we can specify 'hot', 'warm' & 'cold/archive' of the events
for us to access via a dashboard??  Can we specify that the 'hot'
events must be on an SSD, 'warm' on fiber storage & 'cold' on
SATA (or usually it's tapes) if this vendor operates on cloud?

Maybe this question is not technical help but wanted to know what is your opinion.  Last week in a group conversation a colleague said that the United States is storing and has been storing our data on cloud in a facility in UTAH, all text messages, calls land/mobile, web-browsing, etc.

How true is this and should there be any concern?
Can a VPC A in account A use an AWS Private Link or other means to get to a VPC B in account B and then reach a corporate destination over a Direct Connect link connected to VPC B?

Say EC2-1 has and is trying to reach on the corporate network. VPC B with subnet already has a Direct Connect link to the corporate data center and already reach es10.5.5.5. What could I put in place to allow EC2-1 to hop through VPC B and get to

Thank you.
We have 2 systems of different security classifications :
an existing one is critical already in the container/mesosphere
 and another incoming one is low  security.

The mesosphere cluster itself is rather costly.  Can't afford
to set up another cluster just for the new low-security system
& at same time, concerned about co-mingling the 2 in the
same cluster.

We are considering an isolation technique instead of moving the
low-security system to cloud:
the critical system to only run in certain private node while the
low-security (& more medium-low security systems to come)
be run in other private nodes.  Is this isolation considered
secure or we'll need OS/container firewalls or any other mechanisms
to isolate the high-security system from the other systems?
hi experts,

Slightly complex situation here. I'm leading an infrastructure team. At the same time, we've got a service delivery manager who handles all of the change management, incidents etc and is running a rather strict ITIL methodology. We've also got the web team who have now been told that any changes, requests must be put through the service delivery team and that they have to adhere to the ITIL customs.

Now, the web team work with an Agile methodology. So they're pushing back and saying this does not work for them. Trying to see if there is a way to come up with something to get these guys to work together. I've just learned that Agile is not a set of processes but instead a set of values and principles. Which is completely the opposite to what ITIL is.

Have you ever dealt with such a scenario? Do you have any practical advice as to how to best tackle this?

Thanks for helping
Microsoft Teams (And even SharePoint and OneDrive) seem to have grey area with the storage. I can't get a good Microsoft support representative on the phone. I have a project that needs to start with 15TB of file storage and we want to use Microsoft Teams to work on this collaborative project. Is there a license that allows this right off the bat, or is there a way to pay for additional storage?

ie: OneDrive is "Unlimited Storage" but 1TB included, then you have to call when at 90% to get 5TB, and so on and so on. Teams doesn't seem to offer this scaling but we need 15TB to start with.

If Microsoft doesn't have a solution for this, what would be an equivalent?
hi guys

I'm trying to understand vmware hyper convergence in very simple terms and its advantages?

In the current place I'm in, we have multiple sites, each site has a Vmware cluster, vSAN's and also have a cloud footprint.

Does hyper convergence in my current environment mean, mixing the environment we have on site along with cloud? I'm trying to understand this better. If you could explain it in lamen/simple terms that would be great.

Thanks for helping

I am new to cloud computing and have begun my self education by creating a tiny database in a Digital Ocean droplet. Creating and editing are no problem because I have set up SSH keys and distributed them properly (apparently) to the MySQL Workbench on my client PC.

My question: I would like to learn how to connect to my database on the Digital Ocean cloud server from applications that I write on my local client PC's using VB Script. I realize the scope of this question is broad; what I really need is pointed in the right direction. Can someone tell me what resources to use for learning how to do this?

I am fairly adept at manipulating remote databases in the way I described here - just never with databases in the cloud.

Any and all suggestions are welcome. Thank you in advance!

We're considering deploying a Lightsail instance for a client

We need:
Windows Server 2016 Standard - 6 CAL's
SQL Server 2017 - 6 CAL's

So far I've been unable to contact AWS to obtain pricing. I completed a Sales enquiry form a few days ago and have not received a response

1. How to contact AWS to obtain pricing?
2. Assuming I have to wait for AWS to respond, does anyone who use Lightsail have an idea what the pricing is likely to be (we're based in Aust).
3. If we decided to try and deploy via EC2 instead, how would we "size" / convert the above spec into an equivalent EC2 config?

We are looking into options to have some sort of virtual mirror of our current server setup so that if one of the servers goes down the other one takes over and no loss of service.

I need to be a quick study in Docker

I am trying to digest Azure, Containers, Docker, Kubernetes, etc.

and quickly.

I am rebuilding my Mac OS environment to contain:

- a Windows 10 VM on Parallels
- a LINUX VM on Parallels
- Visual Studio 2019 Community Edition
- access to Azure Cloud

So, My first hands on practice could be to learn about Docker.

What kind of work-along tutorial can you suggest?  Or video training?

Reallocating space on my MacBook's 500 GB drive to make room for Azure, Linux and Windows 10

I have a 500 GB drive that's almost filled, but I have allocated 100 GB to my Windows 7 / Parallels (10.4) partition. This "partition" is represented in the form of a file:

Windows 7 (1).pvm

I expect I would upgrade to Parallel's version 14. I NEED to replace Windows 7 with Windows 10. And MAY install Linux, if I need to, to fully use Azure and Containers.

So, how do I create a partition for Linux? Is that something I do also with Parallel's. How much space shall I leave for that?

Any suggestions would be appreciated.
